A field report of this bug on the Squeakland list drew my attention.(*)
This seems to be a regression. The same bug occurs in Squeak Trunk,
but not in Squeak 3.0 (12 years old) where you can happily, though pointlessly,
rotate flaps.
However, the workaround of removing the rotation handle seems fine for
now. (This is done for SugarNavigatorBar in 5.0.1, but not for other flaps.)
Note that if a user tries to rotate a flap from its viewer or a
script, the DNU will also happen, so a deeper workaround should be to
disable all the rotation vocabulary from flap scripting.
It would be nice if we could track down the regression at some point:
not for the cool factor, but just for cleaner code :)
I can see that fullBounds is not being set for the
TransformationMorph, but I can't see why not, so I'll leave that to
those with more experience, if you don't mind.
Have fun! David
