what is "Dojo Name Text Box" onremove event? - dojo

Question

I have a Dojo Name Text Box "xe:djextNameTextBox" on my form. By clicking [x] it removes a name from the list. How do I check what exact name was removed or clicked without parsing all values in getComponent("myNameBox").getValue()?

Answer 1

In my opinion the only way to handle this issue is to parse all values to get the information which name exactly was removed. I had to deal with the same problem in a previous project.
XPage
Set viewScope var "viewFiltersAsString":
<xp:this.beforeRenderResponse><![CDATA[#{javascript:log('beforerenderresponse (start rendering)');
requestScope.start = new Date().getTime();
viewScope.put('viewFiltersAsString', viewController.getViewFiltersAsString());
viewController.actionSetPage();}]]></xp:this.beforeRenderResponse>
Extension Library Dojo Name List Text Box control:
<xe:djextListTextBox id="djFilters" multipleSeparator=","
value="#{viewScope.viewFiltersAsString}" displayLabel="true"
title="Hier klicken um Filter zu löschen">
<xe:this.dataProvider>
<xe:simpleValuePicker caseInsensitive="false"
labelSeparator="~" valueListSeparator=","
valueList="#{viewController.viewFiltersLabelsAsString}">
</xe:simpleValuePicker>
</xe:this.dataProvider>
<xp:eventHandler event="onChange" submit="true" refreshMode="partial"
refreshId="${javascript:compositeData.refreshId}" execMode="partial"
action="#{javascript:viewController.setViewFiltersAsString(#Trim(viewScope.get('viewFiltersAsString')).toString())}">
</xp:eventHandler>
</xe:djextListTextBox>
Managed Bean "viewController"
/**
* Converts all filters to a useable format for dojo List Textbox
* #return string of filters
*/
public String getViewFiltersAsString() {
String filtersAsString = "";
for (ViewFilter filter : viewFilters) {
if (filtersAsString == "") filtersAsString = filter.getKey();
else filtersAsString += "," + filter.getKey();
}
return filtersAsString;
}
public void setViewFiltersAsString(String viewFiltersAsString) {
if (viewFiltersAsString != null && !viewFiltersAsString.equals("")) {
List<String> currentfilters = Converter.toList(",", viewFiltersAsString);
for (ViewFilter filter : viewFilters) {
boolean remove = true;
for (String currentFilter : currentfilters) {
if (filter.getKey().equals(currentFilter)) {
remove = false;
break;
}
}
if (remove) {
// user can click only one filter at one time
setActionViewFilter(viewFilters.removeFilter(filter));
break;
}
}
} else {
setActionViewFilter(viewFilters.removeFilter(viewFilters.get(0)));
}
}
Hint: viewFilters is a java.util.List of ViewFilter objects and a ViewFilter is a simple java class holding information about a filter (in your case a name)
