Re: AjaxCallListener precondition with user input
Hey Sekib,
Thanks a lot for your input!
In case anybody has a similar problem, I ended up solving it through an
AjaxCallListener with a little workaround. If the user confirms the alert,
I re-trigger a click on the link with additional data and check for that in
my precondition. This can be used to perform arbitrary async actions in a
listener precondition.
@Override
> public CharSequence getPrecondition(final Component component) {
>
return "if (attrs.event.extraData != 'OK') { jConfirm(function(r)
> { if (r) { $('#" + component.getMarkupId() + "').trigger('click', 'OK'); }
> }); return false;";
}
Cheers,
Thomas

Re: AjaxCallListener precondition with user input
If this is an option for you, you could use modal dialog from twitter bootstrap (short example can be fond here: https://github.com/sekib/twittermodal). I don't use public CharSequence getPrecondition(final Component component) at all. Modal dialog is shown after clicking the link (no ajax call). Only a click on "Of course" button triggers an ajax call. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/AjaxCallListener-precondition-with-user-input-tp4653566p4653622.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

Hi,
Please create a quickstart and attach it to Jira.

AjaxCallListener precondition with user input
Hey all,
I'm currently in the progress of migrating a largish Wicket 1.5 app to
Wicket 6.2. The only major problem I could not resolve so far are
precondition scripts with user input.
My old code looked like this:
@Override
> public CharSequence postDecorateScript(Component component, CharSequence
> script) {
> return "jConfirm(function(r) { if (r) {" + script + "}});";
> }
The whole script was decorated and the callback only executed if the user
pressed OK in a custom confirmation dialog.
In Wicket 6, there are no more script decorators, just listeners that
provide hooks into the ajax lifecycle, so I changed my code to this:
@Override
> public CharSequence getPrecondition(final Component component) {
> return "jConfirm(function(r) { if (r) { return true; } }); return false;";
> }
The problem is, that the callback function I'm passing to jConfirm is
evaluated only when the user makes a selection, but the precondition has to
return an output immediately. It would work if we used browser-level
confirmation dialogs, but we use a custom jquery dialog for better user
experience.
Is there any way to emulate the pre-Wicket 6 behavior using listeners?
Kind regards,
Thomas
