------------------------------------

             Summary: MarkupContainer#queue doesn't work in table column
                 Key: WICKET-6361
                 URL: https://issues.apache.org/jira/browse/WICKET-6361
             Project: Wicket
          Issue Type: Bug
          Components: wicket
    Affects Versions: 7.6.0
            Reporter: Andrew Geery
            Priority: Minor
         Attachments: myproject.zip

When the AbstractColumn#populateItem adds a Panel which uses the 
MarkupComponent#queue method to add its children, the following error occurs:  
Detach called on component with id 'cell' while it had a non-empty queue.

If the queue methods are changed to add, everything works.  This is the 
workaround.

In the attached file, the problem is ActionPanel (which is added by 
ActionColumn).  Changing queue to add makes the example work.
