wizard starting background task
Hi all,
I'm looking for hints to realize the following scenario:
I have a wizard gathering data. On finish the wizard kicks off a background
task that uses the aforementioned data. On clicking "finish" I would like to
open a new page or even a modal widow that displays a progress bar while the
background task is executing. So far the only working solutions I found are:
1) I start the background task in a lazy load panel, but haven't figured out
yet how to display a progress bar while the lazy load is executing.
2) Open new page and add a form that displays another button to the user
that kicks off the background task. I would really like to avoid the extra
form and button, the finish button of the wizard should be able to do it.
Thanks for your help,
Natalie

Yes, I tried that, too. I'm having problems ordering events.
So I overwrite the finish button which then starts the background task as
well as opens up a modal window with the progress bar.
Szenario 1) The background process is started by the modal window itself and
I need to add a form that automatically clicks the ajax button on load to
start both the progress bar and the background task (how?).
Szenario 2) The background process is started by the finish button of the
wizard. After that the finish button opens up the modal window with the
progress bar. That leaves me with no option to update the progress bar from
the background task, doesn't it?

Simply implement your own FinishButton, e.g. extend AjaxButton and put your logic in it's unSubmit(…) method.
Therefore you will have to override Wizard#newButtonBar(final String id) and provide your own impl, but WizardButtonBar does not have very much logic, so that's acceptable IMHO.

To give you more information:
I can ope a new page (or modal window) and start the wicketstuff progress
bar with a new ajax button on that page.
I can also open a new page with the ajax lazy load panel that will display
the indicating gif while loading stuff in the background.
What I'm looking for is a way to NOT open a new page and NOT to click
another ajax button to start the background task and display the progress
bar. I would like the finish button of the wizard to take care of it.
Now I can of course replace the wizard with a row of pages or panel
replacements, but I don't want to lose the wizard functionality if possible.
Thanks for all your help,
Natalie

You might also take a look at http://wicket.visural.net/examples/submitters (hit the "Calculate X*Y (Modal)" button).

Take a look at wicket-progressbar from Wicketstuff for background processing
and showing a progressbar.
