---------------------------------------
Fix Version/s: (was: 1.4-M3)
> AjaxFallbackDefaultDataTable gives misleading error when fragment markup
> cannot be found
> ----------------------------------------------------------------------------------------
>
> Key: WICKET-1657
> URL: https://issues.apache.org/jira/browse/WICKET-1657
> Project: Wicket
> Issue Type: Improvement
> Components: wicket-extensions
> Affects Versions: 1.3.0-final
> Reporter: Nick Johnson
> Assignee: Igor Vaynberg
> Priority: Minor
>
> If you call cellItem.add(new Fragment("foo","bar", myPage, model), but the
> fragment markup for "bar" isn't found in the markup for myPage,
> AjaxFallbackDefaultDataTable complains, "failed to add a
> component with id [cell] to the provided [cellItem] object." The error
> suggests making sure that cellItem.add was called.
> This error can be misleading, especially since cellItem.add was called. What
> really happened was the fragment with a given ID wasn't found, which should
> really have been an error in its own right.
> It would be nice if the error message gave a better description indicating
> the reason why the component failed to add (e.g., an error in handling the
> Fragment).
