I am Eugene's co-worker. The entire code block would be unreasonable as it
contains alot of business rules that have nothing to do with the technical
issue. The basic code summary is this:
Inside a re-usable panel orgPanel:
final DropDownChoice<StructureL> structureDropDown = new
DropDownChoice<StructureL>("StructureL", StructureLList, structureRenderer);
structureDropDown.add(new AjaxFormComponentUpdatingBehavior("onchange") {
protected void onUpdate(AjaxRequestTarget target) {
//WHOLE lotta code...I'll cut down to the parts that affect the target.
//Note that alot of this is conditional, and different combinations
happen on different conditions
choiceAppl.setChoices(optionsApps);
target.addComponent(choiceAppl);
target.appendJavascript("resetWidth();");
target.appendJavascript("setWidth();");
[...]
target.addComponent(wmc1.setVisible(isVisibleAll));
target.addComponent(wmc2.setVisible(isVisible));
target.addComponent(wmc3.setVisible(isVisibleAll));
target.addComponent(wmc4.setVisible(isVisible));
target.addComponent(structureDropDown);
target.appendJavascript("resetWidth();");
target.appendJavascript("setWidth();");
}
}
Inside a different re-usable panel that is seeking to use the panel but need
to do something extra onchange:
final DropDownChoice struct = (DropDownChoice) orgPanel.get("StructureL");
struct.add(new AjaxFormComponentUpdatingBehavior("onchange") {
private static final long serialVersionUID = 1L;
@Override
protected void onUpdate(AjaxRequestTarget target) {
onOfficeChange(target, struct, org1, org2, org3, org4);
}
});
[...]
private void onOfficeChange(AjaxRequestTarget target, DropDownChoice struct,
DropDownChoice org1, DropDownChoice org2, DropDownChoice org3,
DropDownChoice org4) {
List<String> users = loadUsersByOfficeInfo(target, struct.getInput(),
org1.getInput(), org2.getInput(), org3.getInput(), org4.getInput());
if(users != null) {
listUsers.setChoices(users);
target.addComponent(listUsers);
listUsersFromOffice.setChoices(users);
target.addComponent(listUsersFromOffice);
}
}
Note that the list* controls are both ListMultipleChoice and the structure
control are others within orgPanel are DropDownChoices.
The behavior is that the panel within the panel in my page works fine if i
don't add a second AjaxFormComponentUpdatingBehavior to the same event.
When I add my second event, the second works perfectly. But the original is
never called (confirmed by both breakpoint and print statement), breaking
the behavior of that component.
