Frank Bille Jensen updated WICKET-1345:
---------------------------------------
Fix Version/s: (was: 1.3.3)
> Link#onClick does not fire in specific case.
> --------------------------------------------
>
> Key: WICKET-1345
> URL: https://issues.apache.org/jira/browse/WICKET-1345
> Project: Wicket
> Issue Type: Bug
> Components: wicket
> Affects Versions: 1.3.1
> Environment: tested on freebsd jvm-1.6 and linux jvm-1.6
> Reporter: Victor Igumnov
> Assignee: Johan Compagner
> Priority: Critical
>
> Here is the test case that triggers it.
> LeaveGroupLink works *perfectly* if on a page as-is; it is visible and
> onClick() fires. However, if I add LeaveGroupLink to a repeater (listview),
> the link is visible but onClick() does not fire. I scanned around the wicket
> source and noticed a comment about component callback won't execute if
> isVisible is false. So the component *renders* but onClick is never fired
> when Link is in a repeater component.
> public class LeaveGroupLink extends Link {
> private static final long serialVersionUID = 1L;
> public LeaveGroupLink(final String id, final IModel model) {
> super(id, model);
> }
> @Override
> public void onClick() {
> // did some basic println message to see if it fired. No message displayed
> WebAppSession sess = (WebAppSession) Session.get();
> Group g = (Group) getModelObject();
> sess.getGroupService().leaveGroup(g, sess.getUser());
> }
> @Override
> public boolean isVisible() {
> WebAppSession sess = (WebAppSession) Session.get();
> Group g = (Group) getModelObject();
> // I made sure this turns true or false... not a service level issue.
> return sess.getUser().getGroupMembership().contains(g);
> }
> }
> Here is the work around that works in a repeater .
> public class LeaveGroupLink extends Link {
> private static final long serialVersionUID = 1L;
> public LeaveGroupLink(final String id, final IModel model) {
> super(id, model);
> }
> @Override
> public void onClick() {
> // did some basic println message to see if it fired. No message displayed
> WebAppSession sess = (WebAppSession) Session.get();
> Group g = (Group) getModelObject();
> sess.getGroupService().leaveGroup(g, sess.getUser());
> }
> @Override
> protected void onBeforeRender() {
> super.onBeforeRender();
> WebAppSession sess = (WebAppSession) Session.get();
> Group g = (Group) getModelObject();
> setVisible(sess.getUser().getGroupMembership().contains(g));
> }
> }
> If I use it like this, it works correctly in the repeater.
