ajax event not quite working as planned
I have a listview where each row has an expandable section in it to show
additonal detail on some rows. That works. But two aspects aren't working.
1) I am trying to change the + on the button to a -, and then back again
when we collapse. My code looks like:
if(invokingButton.getLabel().getObject().equals(+))
invokingButton.setLabel(new ModelString(-));
else
invokingButton.setLabel(new ModelString(+));
target.add(invokingButton);
The label never changes. From stepping in, I can say that yes, the label
set to - line does run when expected. yes, outputmarkupId is set to true.
Button code when created:
item.add(new AjaxButton(btnExpander){
private static final long
serialVersionUID = 1L;
public void onSubmit(AjaxRequestTarget
target, Form form) {
onActivityLogExpansion(target,
this, activity);
}
}.setLabel(new ModelString(+))
.setOutputMarkupId(true).setVisible(showReject ||
showSubmit)
.setOutputMarkupPlaceholderTag(true));
2) When I go to collapse the row, the event gets to the server, things seem
to work stepping through the code, but then the region does not collapse and
I get the following in the wicket ajax debug:
INFO:
?xml version=1.0 encoding=UTF-8?ajax-responsecomponent
id=expandableWhenReject4c /componentcomponent id=btnExpander47
/componentheader-contribution encoding=wicket1
/header-contributionevaluate/evaluate/ajax-response
ERROR: Wicket.Ajax.Call.processComponent: Component with id
[[expandableWhenReject4c]] was not found while trying to perform markup
update. Make sure you called component.setOutputMarkupId(true) on the
component whose markup you are trying to update.
INFO: Response processed successfully.
INFO: refocus last focused component not needed/allowed
INFO: focus set on wicketDebugLink

The container being hidden is created as:
WebMarkupContainer expandableReject = new
WebMarkupContainer(expandableWhenReject, new
ModelShareActivityPlusDecode((ShareActivityPlusDecode)
item.getDefaultModel().getObject()));
expandableReject.setVisible(false);
expandableReject.setOutputMarkupId(true);
expandableReject.setOutputMarkupPlaceholderTag(true);
and in the event:
WebMarkupContainer wmc = (WebMarkupContainer)
invokingButton.getParent().get(expandableWhenReject);
wmc.setVisible(!wmc.isVisible());
target.add(wmc);

Re: ajax event not quite working as planned
Setting that AND adding the form that contains the list to the target (which was inspired by that bit of text) seems to have solved issue #2, the collapse. Thanks! However, issue #1, the button label, is still not working correctly. Any insight there? -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/ajax-event-not-quite-working-as-planned-tp4665083p4665085.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
