Re: [JIRA] Commented: (SQ-1119) Rotating flaps DNU and other mishaps

    [ http://tracker.squeakland.org/browse/SQ-1119?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=40892#action_40892 ]

Karl Ramberg commented on SQ-1119:
----------------------------------

It is really the FlapTab that has some issues with rotation.

Somehow the TransformationMorph fails with nil fullBounds.

I'm not sure how that can happen...

> Most flaps can be rotated by rotation handle but none of them do this gracefully. Viewer flaps give DNU when collapsed and opened again. 'About' flap leaves a green transformation morph on the desktop.
> Should we disable  the rotation handle for flaps ?
> I can't really see a use case for rotating a flap, except for a cool factor ;-)
