tabbedpanel (and ajaxtabbedpanel) only submit the selected tab. A mode which
instead submits all loaded tabs would be helpful.

Key: WICKET-2579
URL: https://issues.apache.org/jira/browse/WICKET-2579
Project: Wicket
Issue Type: Wish
Components: wicket-extensions
Affects Versions: 1.4.3
Reporter: Roger Armstrong
If I want to split the contents of a form across multiple tabs (for example a
user profile form split into basic and advanced settings), there seems to be no
way to validate the form properly.
The user should be able to fill out, say, first name and last name in the basic
tab, then switch to the advanced tab and fill out some settings there, then
click the Save button. If the user forgot to fill out a required field on the
basic, (say, email address), there's no way to handle this (because the first
tab is already gone when you switch to the second tab).
I've tried to use an AjaxFormValidatingBehavior on blur of all form components,
but this is not a good solution since validation occurs on lost focus instead
of when the user clicks the Save button.
What I would like would be that the TabbedPanel keeps all visited panels around
(but all hidden except the selected tab) so that they are all submitted
together. That way, you have lazy loading, but standard submit and validate
behavior (at the expense of keeping the loaded panels around).
This seems like a fairly standard pattern for using a tabbed panel, so it would
seem useful to have it in the "standard" tab panel instead of everyone having
to reinvent it (like at
http://www.xaloon.org/blog/advanced-wicket-tabs-with-jquery).
