In my case , I got Exception
if (holder.isScrap() || holder.itemView.getParent() != null) {
throw new IllegalArgumentException(
"Scrapped or attached views may not be recycled. isScrap:"
+ holder.isScrap() + " isAttached:"
+ (holder.itemView.getParent() != null));
}
and holder.itemView.getParent() == true.
I do not use android:animateLayoutChanges and I donn't want use "setHasStableIds(true)" , but I don't know why holder.itemView.getParent is true. Maybe someone can give me a solution or a link, thx

I want to delete many managed objects, selected by fragment type. There are more then 2000 elements in it. Unfortunately I can not delete all with one function call. I have to call this function many times until I have deleted all. How can I delete a list of managed objects in a sufficient way? Not defining page size did not help...
This is my current function:
InventoryFilter filter = new InventoryFilter();
filter.byFragmentType("xy_fragment");
ManagedObjectCollection moc = inventoryApi.getManagedObjectsByFilter(filter);
int count = 0;
// max page size is 2000
for (ManagedObjectRepresentation mo : moc.get(2000).allPages()) {
if (mo.get("c8y_IsBinary") != null) {
binariesApi.deleteFile(mo.getId());
} else {
inventoryApi.delete(mo.getId());
}
LOG.debug(count + " remove: " + mo.getName() + ", " + mo.getType());
count++;
}
LOG.info("all objectes removed, count:" + count);
By calling moc.get(2000).allPages() you already obtain an iterator that queries following pages on demand as you iterate over it.
The problem you are facing is caused by deleting elements from the same list you are iterating over. You delete element from the first page, but once the second page is queried from the server it does not contain the expected elements anymore because you already deleted the first page. Now all elements are shifted forward by your page size.
You can avoid all of that by making a local copy of all elements you want to delete first:
List<ManagedObjectRepresentation> allObjects = Lists.newArrayList( moc.get(2000).allPages())
for (ManagedObjectRepresentation mo : allObjects) {
//delete here
}
There is no bulk delete allowed on the inventory API so your method of looping through the objects is the correct approach.
A bulk delete is already a dangerous tool on the other APIs but on the inventory API it would give you the potential to accidentally delete all your data with just one call (as all data associated with a managedObject is also deleted upon the deletion of the managedObject).
That is why it is not available.
I solved the problem by calling the method until no elements can be found any more. It is not nice but I have no other idea.
public synchronized void removeManagedObjects(String deviceTypeKey) {
int count = 0;
do {
count = deleteManagedObjectes(deviceTypeKey);
}while(count > 0);
}
private int deleteManagedObjectes(String deviceTypeKey) {
InventoryFilter filter = new InventoryFilter();
filter.byFragmentType("xy_fragment");
ManagedObjectCollection moc = inventoryApi.getManagedObjectsByFilter(filter);
int count = 0;
if(moc == null) {
LOG.info("ManagedObjectCollection are NULL");
return count;
}
for (ManagedObjectRepresentation mo : moc.get(2000).allPages()) {
if (mo.get("c8y_IsBinary") != null) {
binariesApi.deleteFile(mo.getId());
} else {
inventoryApi.delete(mo.getId());
}
LOG.debug(count + " remove: " + mo.getName() + ", " + mo.getType());
count++;
}
LOG.info("all objectes removed, count:" + count);
return count;
}
I am having an error when trying to sort doing a findAll:
"Sort key dateis not one of the valid strings."
My options are the following (I tried different formats for desc, everyone was throwing the same 'error'):
var options = {sort: [{"date": "desc"}]};
Everything seems fine, the JSONStore works as expected, sorting the returned data, I just want to be sure that the 'error' is indeed a bug or mistake on the worklight.js part and not that I am doing something wrong.
This is the function that checks for a valid sortObj in worklight.js:
/** Checks if sortObj is a valid sort object for a query
* #private
*/
var __isValidSortObject = function(sortObj, searchFields, additionalSearchFields) {
var propertiesValidated = 0,
sortObjKey, sortStr;
for (sortObjKey in sortObj) {
if (sortObj.hasOwnProperty(sortObjKey)) {
if (propertiesValidated > 0) {
WL.Logger.trace('Sort object ' + JSON.stringify(sortObj) + ' has more than one property. Each object must have only one property.');
return false;
}
//check is sortObjKey is lowerCase
if (_.isUndefined(searchFields[sortObjKey.toLowerCase()]) && _.isUndefined(additionalSearchFields[sortObjKey.toLowerCase()])) {
WL.Logger.trace('Sort key ' + sortObjKey + ' is not part of search fields: ' + JSON.stringify(searchFields) + ' or additional search fields: ' + JSON.stringify(additionalSearchFields));
return false;
}
sortStr = sortObj[sortObjKey];
//Check that the string that specifies sorting order says either "asc" or "desc"
**if (__isString(sortStr) && sortStr.length > 0 && (/^(a|de)sc$/i.test(sortStr))) {
WL.Logger.trace('Sort key ' + sortObjKey + 'is not one of the valid strings.');
propertiesValidated++;
} else {
// Here seems to be the problem, shouldn't the trace be before return false?
return false;
}**
}
}
if (propertiesValidated === 0) {
return false;
}
return true;
};
You can clearly see that they do the WL.Logger.trace when the check is fine and that it should be just before return false.
Does anyone that has used sort on a JSONStore receives this trace as well?.

I contacted IBM support and they indeed confirmed that it is a bug that will be solved in the next build.
Hello I a little problem with my paginator, i would like to use some custom SQL Request but each time i click on a paginator link it loads my model without the custom request
I enter informations on a form that I send by GET method:
$view->grid->js()->reload(array("From" =>
$form->get("From"),"To" => $form->get("To"),"SSID" => $form->get("SSID")))
->execute();
On my view I have :
$this->request=$this->api->db->dsql();
$this->grid=$this->add('Grid');
$this->grid->setModel('Systemevents',array('ID','ReceivedAt','Message'));
$this->grid->addPaginator(10);
if (isset($_GET["SSID"])) {
$this->ssid = $_GET["SSID"];
}
if (isset($_GET["From"])) {
$this->from = $_GET["From"];
}
if (isset($_GET["To"])) {
$this->to = $_GET["To"];
}
$this->grid->dq->where($this->requette->expr('Message like "%.% '
. $this->ssid . ' % src=%"'))
->where($this->requette->expr("ReceivedAt >= '".$this->from. "'
AND ReceivedAt <= '".$this->to."'"));
The problem is that the where condition disapear when i change the page with the paginator.
I did not found any solution to my problem so I have done something differently
I added two buttons to my grid wich allows me to change the limit of the sql request.
The previous button is hidden if the limit is 0.
Now i have to found how to count the number of lines (select count('ID') from 'SystemEvents' where....) and to stock it in a variable.
Finally the ultimate solution was to do :
if ((isset($_GET["SSID"])) || (isset($_GET["From"])) || (isset($_GET["To"]))) {
//GET Method from Recherche.php
$this->ssid = ($_GET["SSID"] == "null" ? null : $_GET["SSID"]);
$this->api->stickyGET("SSID"); // the solutiuon is here
$this->from = ($_GET["From"] == "null" ? null : $_GET["From"]);
$this->api->stickyGET("From"); // <===== the solutiuon is here
$this->to = ($_GET["To"] == "null" ? null : $_GET["To"]);
$this->api->stickyGET("To"); // <===== the solutiuon is here
}
Okay, I have a WCF service which is going to be acting as a way to access my SQL database. That part has become largely irrelevant to this question, since for some reason my WCF service crashes. Or, at least, it causes my client Silverlight application to crash. This is why I come here to ask you guys about it.
So here's the code. Bear in mind that it is called asynchronously from my Silverlight client. When it is done, the string that is returned from this method is put on the screen for the client.
public string AddClients(IEnumerable<Client> newClients)
{
int nAdded = 0;
int nelse = 0;
string str = "";
List<Client> newClientsList = newClients.ToList();
List<Client> existingClients = dc.Clients.ToList();
List<Client> clientsToAdd = new List<Client>();
return newClientsList.Count.ToString();
foreach (Client client in newClientsList)
{
var clt = existingClients.FirstOrDefault(c => c.ClientName == client.ClientName);
if (clt == null)
{
return clt.ClientName;
//str = str + " found: " + clt.ClientName + "\n";
//dc.Clients.(clt);
//existingClients.Add(clt);
// clientsToAdd.Add(clt);
nAdded++;
}
else
{
nelse++;
}
}
if (nAdded > 0)
{
//str = str + " more than one nAdded";
// dc.Clients.InsertAllOnSubmit(clientsToAdd);
// dc.SubmitChanges();
}
return nelse.ToString();
}
You may be able to figure out what's supposed to be happening, but most of it's not happening now due to the fact that it's not working out for me very well.
At the moment, as you can see, there is a return quite early on (before the foreach). With things as they are, that works okay. You press a button in the client, it makes the call, and then returns. So as it is, you get '3' returned as a string (this is the size of newClients, the parameter). That is okay, and at least proves that the service can be connected to, that it returns messages okay, and what not.
If I remove that top most return, this is where it gets interesting (well, problematic). It should either return clt.ClientName, in the if (clt==null) condition, or it should return nelse.ToString() which is right at the end.
What do I actually get? Nothing. The method for the completion never seems to get called (the message box it shows never appears).
I've commented most of the stuff out. Surely it has to get to one of these conditions! Have I missed something really obvious here? I really have been attempting to debug this for ages, but nothing! Can someone see something obvious that I can't see?
For the record, 'dc' is the data context, and dc.Clients is a list of Client entities.
I could be missing something, but won't this throw a NullReferenceException? That has to be at least part of your problem.
if (clt == null)
{
return clt.ClientName;
...
I dont understand why you are trying to return the name of the first newly found client from the list you received. Why not just return an integer with total count of newly found clients that you are inserting in the database.
Try:
public string AddClients(IEnumerable<Client> newClients)
{
string str = "";
List<Client> newClientsList = newClients.ToList();
//to save processor and network
List<string> existingClients = dc.Clients.Select(x => x.ClientName).ToList();
List<Client> clientsToAdd = (from nc in newClientsList
join ec in existingClients on nc.ClientName equals ec into nec
from ec in nec.DefaultIfEmpty()
where ec == null
select nc).ToList();
if (clientsToAdd.Count > 0)
{
dc.Clients.InsertAllOnSubmit(clientsToAdd);
foreach (Client c in clientsToAdd)
str += "found: " + c.ClientName + "\n";
return str;
}
return "0 new clients found";
}
easier, simpler, cleaner.
I'm really struggling with a bug that did not appear on my dev environment, only once deployed in test.
I'm using a prepared Statement to run around 30 000 query in a row. The query check for the similarity of a string with what's in our database, using the oracle fuzzy method.
The column checked is indexed, but, don't know why, it fails randomly after some iterations, saying that index does not exists.
I don't understand what's going on, as the index really exists. My method never rebuild or delete the index so there is no reason for this error to appear ...
public List<EntryToCheck> checkEntriesOnSuspiciousElement(List<EntryToCheck> entries, int type,int score, int numresults, int percentage) throws Exception {
Connection connection = null;
PreparedStatement statementFirstName = null;
PreparedStatement statementLastname = null;
int finalScore = checkScore(score);
int finalNumResults = checkNumResults(numresults);
int finalPercentage = checkPercentage(percentage);
try {
connection = dataSource.getConnection();
StringBuilder requestLastNameOnly = new StringBuilder("SELECT SE.ELEMENT_ID, SE.LASTNAME||' '||SE.FIRSTNAME AS ELEMENT, SCORE(1) AS SCORE ");
requestLastNameOnly.append("FROM BL_SUSPICIOUS_ELEMENT SE ");
requestLastNameOnly.append("WHERE CONTAINS(SE.LASTNAME, 'fuzzy({' || ? || '},' || ? || ',' || ? || ', weight)', 1)>? ");
requestLastNameOnly.append((type > 0 ? "AND SE.ELEMENT_TYPE_ID = ? " : " "));
requestLastNameOnly.append("ORDER BY SCORE DESC");
statementLastname = connection.prepareStatement(requestLastNameOnly.toString());
for (EntryToCheck entryToCheck : entries) {
ResultSet rs;
boolean withFirstName = (entryToCheck.getEntryFirstname() != null && !entryToCheck.getEntryFirstname().equals(""));
statementLastname.setString(1, entryToCheck.getEntryLastname().replaceAll("'","''"));
statementLastname.setInt(2, finalScore);
statementLastname.setInt(3, finalNumResults);
statementLastname.setInt(4, finalPercentage);
if(type > 0){
statementLastname.setInt(5, type);
}
System.out.println("Query LastName : " + entryToCheck.getEntryLastname().replaceAll("'","''") );
rs = statementLastname.executeQuery();
while (rs.next()) {
Alert alert = new Alert();
alert.setEntryToCheck(entryToCheck);
alert.setAlertStatus(new AlertStatus(new Integer(AlertStatusId.NEW)));
alert.setAlertDate(new Date());
alert.setBlSuspiciousElement(new BlSuspiciousElement(new Integer(rs.getInt("ELEMENT_ID"))));
alert.setMatching(rs.getString("ELEMENT") + " (" + rs.getInt("SCORE") + "%)");
entryToCheck.addAlert(alert);
}
}
}
catch (Exception e) {
e.printStackTrace();
throw e;
}
finally {
DAOUtils.closeConnection(connection, statementLastname);
}
return entries;
}
Really don't know what to look at ...
Thanks !

I never used Oracle text tables but my advice is:
Make sure that no one else is executing DDL statements on the table simultaneously.
Also, make sure that, index you have is context index.
Create an index for your column where you want to apply search
........................................
CREATE INDEX "MTU219"."SEARCHFILTER" ON "BL_SUSPICIOUS_ELEMENT " ("LASTNAME")
INDEXTYPE IS "CTXSYS"."CONTEXT" PARAMETERS ('storage CTXSYS.ST_MTED_NORMAL SYNC(ON COMMIT)');
