Igor Vaynberg commented on WICKET-2482:
---------------------------------------
yes, repeaters and forms do not play well together on stateless pages. even if
we attempted to repopulate the dataview there is no guarantee the same data
would be shown - so you may end up with the same error or worse, having a
different object put into your model then the one the user originally selected.
you are better off using a stateful page.
> Checkgroup doens't work with stateless pages and listview

> I think this is related to:
> https://issues.apache.org/jira/browse/WICKET-1545
> When using checkgroup with listviews and stateless pages, checkgroup is not
> able to convertValues. The cause seems that listview onbeforeRender is never
> called on form submission. Thus children are never populated and check is not
> added to the hierarchy.
> The following error appears:
> submitted http post value [12345] for CheckGroup component
> [0:form:checkGroup] contains an illegal relative path element [12345] which
> does not point to a Check component. Due to this the CheckGroup component
> cannot resolve the selected Check component pointed to by the illegal value.
> A possible reason is that componment hierarchy changed between rendering and
> form submission
> I'm using a stateless check component, that overides getValue.
