I have an interactive report on a page in my application. I created a filter at the top of the dashboard that causes the whole page to refresh. Everything looks good but when I go to download the report it reverts the downloaded data back to the default date ranges. Any ideas on how to fix this?
I see the page refresh is refreshing your page item value too.
there are two options you can try.
Setting Session state on item change by executing the below code using dynamic action.
BEGIN
APEX_UTIL.set_session_state('P1_DEPTNO', 30);
END;
Stop Refreshing the page

I've got an issue due to a timing issue with react-admin, that i'm looking for a little help on.
The situation is where user A creates a resource, and user B, on a different PC, then goes to list and edit that resource.
For user B, the list page loads the full dataset of 10 resources, then the edit page re-loads the single resource that is being edited.
However, the specific process on the edit page seems to be:
Render page
Render resource cached from the list page
Request the single resource from the API
Populate the edit form with the updated values from the API
Set the form to dirty
That last point is critical, since I have an action button that is only enabled if the form is pristine, so the user has to save any changes before triggering the action.
But in this case, the list view and the edit view seem to return the same data for the resource, so I'm not sure why the form is being set to dirty.
Any thoughts?
Regards,
Andy
This isn't a complete answer, but I hope it helps you save some time. I recently upgraded React Admin version from 3.5.3 to 3.6.0. I noticed that the Save button is now sometimes disabled unexpectedly, and inconsistently. For example, I may navigate to the edit view of a resource by clicking a link and the Save button is enabled, but if I refresh the page, the Save button is disabled. Apparently, the Save button is supposed to be disabled when the form is pristine. So between 3.5.3 and 3.6.0, it seems that some changes were made to either the pristine handling or the Save button's reaction to pristine, and it is not working consistently.
I see there is a new issue opened three days ago regarding overriding the Save button behavior, wrt pristine. https://github.com/marmelab/react-admin/issues/4913 . So, it seems the dust hasn't settled on this behavior. Perhaps a bug will be found.
I have a page with a viewPanel and a dialog. When an item in the viewPanel is clicked, the dialog opens, prompting the user to make changes to that item, and offering them the option to generate a report of the item in PDF format.
At first, I tried putting the PDF creation onto a button, as described here: http://www.eknori.de/2011-10-25/xpages-to-pdf-with-itext/ However, whenever the button is pressed, I get a "NotFoundError: DOM Exception 8" which seems to stem from the dojo JS. So currently I have an alternative whereby the button simply sets some sessionScope variables and opens a pdf.xsp XPage, where the variables are read back and the PDF is created.
The PDF gets created correctly, but it also means that the page that the user is on won't be refreshed to display their new change in the viewPanel. I've tried adding page redirects at the bottom of the XPage which creates the PDF, but with no luck.
So, how can I create a PDF and prompt a user to download it, but also refresh the page that they are currently on?
Are you isseuing an partial refresh on the button to hide your dialog and to execute the code for pdf generation? If so you I think that there is your problem. What you could do is to do a partial refresh on the onClose() method of the dialog to refresh the viewpanel. In the clientside onunload method you could open a so called xAgent which renders the pdf for you in a new window (window.open(pdf.xsp?docid=xxx). Take a look here: NotesIn9: 039 Creating PDF’s with XPages Part 2
Of cours the problem with this approach is that when you have a button / image in yoru viewpanel row that displays if the report has been created is not shown because the xagent runs after the / during the time the viewpanel row is being refreshed.
I am implementing a series of rdlc reports on a webpage using a ReportViewer. When the report is initially generated is works fine but when I try to change the page of the report the following error is displayed:
"One or more data sources is missing credentials"
I have checked that the Data Source of the Local report is set correctly and the fact that the first page of the report is correctly displayed is proof of this.
When I export the report to a PDF or any other format it correctly includes all the report pages.
I have also tried implementing the PageNavigation event but this error is thrown before the event is called.
Does any one have any incite into this issue and what solution there may be?
Ok I found the the problem. I had a setting AsyncRendering set to false in order enable the reportviewer to stretch to the full width of the page.
Unfortunately this causes a postback and the enitre page is reloaded and obviously the datasource is lost.
Unfortunate as I will now have to manage the width of the reportviewer manually and it does not look great.
Anyway solution is to ensure AsyncRendering = true.
I have rails application that calculates prices of goods and I set prices in session. I have 'back' button in my application. When I clicks on 'back' link, I will get my previous session values like 'prices','goods' I purchased.
But when I clicks on 'browsers' back button,I won't get my session values, I have to refresh the page for that.
I'd say you have caching issues... The browser remembers what it saw before, and thinks it's the same (without even going to the trouble to ask the server any more). Try if this article helps
You probably want to prevent the browser from caching your pages so that they get refreshed when the user clicks the Back button. This article should help.
I'm writing an intranet ASP.NET page using VB.NET. I've run into a particularly nasty problem dealing with handling file uploads. I'll do my best to explain the problem, and perhaps someone can help.
My problem is almost a duplicate of this one, or this one, except (other than the filename) I don't care about sending the file to the server until the other data has been reviewed.
Here's the situation:
Joe Q. Dataentry inputs some data into several fields. The first 3 are drop down, and when he changes the selection, a postback event is fired that queries a database for valid entries for the other drop down selections. After selecting the values, he inputs some other data, chooses a file to accompany the data and clicks the "Update" button. When he hits the button, it fires a postback event that sends the current data to the server to be validated. The data will create a change in the database, so he is presented with a view of the current state, and what it will look like when his changes are made. He can now either confirm or cancel the operation for whatever reason.
Part of the data he will see involves the extension of the file which may be a PDF, or could also be some image file or other document.
Now here's where my problem is - on each postback event, the fileupload dialog is cleared. I was getting around it by creating a temporary file on the first postback and then renaming if he clicks OK or deleting on Cancel... but I need to do a variety of things, based on the previous state of data and the filename. I've tried to keep some session variables to retain the filename, and that works OK for just renaming the file, but for what I need to do it gets unwieldy.
What I want to do is be able to have the postback event to present the changes, and then when the user clicks "OK", submit the file. Is there any possible way to do that?
One of my thoughts was to do some of the validation client-side (I'm already re-validating server side so I'm not too worried about data security there), but I don't know how I could get the information from the database query.
Thanks for any help, and reading my slightly convoluted story/situation!
EDIT:
It appears that what I want to do is prevent a certain button from firing a full postback. Is there any way to do that?
EDIT II:
I have an update panel on the page already - is there any way for the button to only post what's in the update panel?
What you might want to do is place your drop-downs inside of an ASP.NET AJAX UpdatePanel, and keep your file upload control out of that.
Your update panel will do the post backs and allow your validation logic to happen without submitting the file, then when you hit your final "Save" button (which is also outside of your UpdatePanel) the entire form will be submitted back and you can work with your file then.
