Re: jquery DataTable + wicket Cannot bind a listener
Hi,
Try with Ajax loading of the new pages.
I am not sure how DataTables removes and re-adds the rows later. It should
use jQuery's clone(true, true) to preserve the event bindings. Ask in their
forums.

jquery datatables removes DOM elements when configured for pagination.
This means the AjaxLinks in my listview generate wicket javascript like:
Wicket.Ajax.ajax({u:./executed?7-1.IBehaviorListener.0-container-
executedTransactionPanel-executedListView-0-detailsLink,e:click,c:
detailsLinkff});;
Wicket.Ajax.ajax({u:./executed?7-1.IBehaviorListener.0-container-
executedTransactionPanel-executedListView-1-detailsLink,e:click,c:
detailsLink100});;
Wicket.Ajax.ajax({u:./executed?7-1.IBehaviorListener.0-container-
executedTransactionPanel-executedListView-2-detailsLink,e:click,c:
detailsLink101});;
Wicket.Ajax.ajax({u:./executed?7-1.IBehaviorListener.0-container-
executedTransactionPanel-executedListView-3-detailsLink,e:click,c:
detailsLink102});;
...
If the table has 2 pages, it removes the DOM elements from the 2nd page so
I get the wicket debug error Wicket.Ajax: Cannot bind a listener for
event click on element elementId because the element is not in the DOM
Now when I hit the link for next page of the table, the DOM has been
updated to reflect the rows, but the javascript events need to be added
again and so the links are broken.
Is there any good way to do this?
Thanks, Jason

Re: Wicket error page runs twice
Well, you are definitely right that there are multiple requests for whatever reason. I can see WicketServlet doPost called, the method runs, throws the error, the error page gets control with the exception, then a doGet occurs and the error page runs again without the exception. I can't really see the details as I don't have the source for Wicket 6.12.0. I went to http://www.apache.org/dyn/closer.cgi/wicket/6.12.0 and none of the links work. Where can I download 6.12.0 source so I can attach it to my debugger? -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Wicket-error-page-runs-twice-tp4668093p4668111.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

Re: Wicket error page runs twice
Okay, I found this, the first request URL and query string are:
/EquitableSharing/?19-1.IBehaviorListener.1-share-form-toolContainer-declineSharingButton
The second is:
/EquitableSharing/wicket/bookmarkable/gov.usdoj.afms.esp.application.ESPApplicationErrorPage
So it seems like even though the error page RUNS in the first request,
wicket is trying to redirect to it in order to make the URL bookmarkable.
Of course, nobody wants a bookmarkable error page, that would just be silly.
So I must be triggering this behavior by accident somewhere.
The error page itself just extends WebPage. In the app init, the error page
is set up like so:
// set the error page
IApplicationSettings settings = getApplicationSettings();
settings.setInternalErrorPage(ESPApplicationErrorPage.class);
this.getRequestCycleListeners().add(new
AbstractRequestCycleListener(){
public IRequestHandler onException(RequestCycle cycle,
Exception ex) {
cycle.setMetaData(EXCEPTION_KEY, ex);
return null;
//cycle.getRequestHandlerScheduledAfterCurrent();
}
});
getExceptionSettings().setUnexpectedExceptionDisplay(IExceptionSettings.SHOW_INTERNAL_ERROR_PAGE);
We have some calls to mountPage in the app init, but the error page is not
involved. Where is this behavior coming from I wonder?

Re: Wicket error page runs twice
With a slight modification, that worked. I used: return new RenderPageRequestHandler(new PageProvider(new ESPApplicationErrorPage(ex))); Thanks Martin! -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Wicket-error-page-runs-twice-tp4668093p4668115.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
Re: jquery DataTable + wicket Cannot bind a listener
Hi Martin,
Thanks for the help-- I've reached out to them, the js appears pretty
complex
http://cdn.datatables.net/1.10.3/js/jquery.dataTables.js
They indicate that listeners need to be added according to:
http://www.datatables.net/examples/advanced_init/events_live.html
Is there any kind of mode in wicket possibly that would preserve the
listeners in this way?
Thanks, Jason
