How to update a label BEFORE a form is submitted?
Still looking for help on how to update page components before a long running
page submit. I don't seem to see the light on chaining events from same
button so if someone can provide an example it would be greatly appreciated.
1) User presses submit button
2) A label gets updated saying "button pressed!"
3) Then the submit is processed
Seems I can do this with the ajax self updating timer behavior or mixing
client-side javascript with wicket components but that just doesn't seem
right for my scenario. Any working example of any sort will help though.

Thanks Martin. I am back on track after looking at those link examples and
the source code for AjaxIndicatorAppender.

Hi,
Check IAjaxCallDecorator.
With a decorator you can change the label with pure JavaScript and
after that let Wicket do its Ajax call.
http://www.wicket-library.com/wicket-examples/ajax/links -> Success
link shows an alert(). Just change that JS to update a label.
