> Key: WICKET-2152
> URL: https://issues.apache.org/jira/browse/WICKET-2152
> Project: Wicket
> Issue Type: Improvement
> Components: wicket
> Affects Versions: 1.3.5, 1.4-M3, 1.5-M1
> Environment: All
> Reporter: Daniel Toffetti
> Priority: Trivial
>
> My use case is: I have a page with an AjaxSelfUpdatingTimerBehavior and a
> button that opens a modal window. If the modal window is opened and the timer
> fires the refresh, the browser ask for a confirmation to leave the page, and
> then closes the modal window.
> It would be very nice to be able to stop the self updating behavior just
> before opening the modal window, and restarting it just before closing it.
> This feature has already been requested long ago in SourceForge tracker, see:
> http://www.nabble.com/forum/ViewPost.jtp?post=5773807&framed=y, but couldn't
> find it in JIRA.
> To overcome this problem, I created a custom (AbstractAjax +
> AjaxSelfUpdating)TimerBehavior, and added this method:
> /**
> * Starts the timer
> */
> public final void start(final AjaxRequestTarget target)
> {
> stopped = false;
> target.getHeaderResponse().renderOnLoadJavascript(
>
> getJsTimeoutCall(updateInterval));
> }
> And changed (this might not be important, I'm not sure but this works for me):
> /**
> *
> * @see
> org.apache.wicket.ajax.AbstractDefaultAjaxBehavior#respond(org.apache.wicket.ajax.AjaxRequestTarget)
> */
> protected final void respond(final AjaxRequestTarget target)
> {
> onTimer(target);
> if (!stopped) {
> target.getHeaderResponse().renderOnLoadJavascript(
>
> getJsTimeoutCall(updateInterval));
> }
> }
> to:
> /**
> *
> * @see
> org.apache.wicket.ajax.AbstractDefaultAjaxBehavior#respond(org.apache.wicket.ajax.AjaxRequestTarget)
> */
> protected final void respond(final AjaxRequestTarget target)
> {
> if (!stopped) {
> onTimer(target);
> target.getHeaderResponse().renderOnLoadJavascript(
>
> getJsTimeoutCall(updateInterval));
> }
> }
> Then in the onClick of the button that opens the modal window, I call;
> @Override
> public void onClick(AjaxRequestTarget target) {
> autoRefreshBehavior.stop();
> //---
> and in the onClose of the modal window:
> @Override
> public void onClose(AjaxRequestTarget target) {
> //---
> autoRefreshBehavior.start(target);
> }
> It's working fine so far, but it would be nice to have this little feature or
> something similar provided in core.
