The should be a dispatch to not expose widget in:
aTab buildWidget widget

Then, this 
 aTab ensureMorphicAdapter asWidget 

looks really weird.

Could you provide more info about the DNU or should I try to read your mind? :P

Hi,

I was playing with Spec and I ran into a DNU problem when trying to add dynamically tabs. Looks for me that this:

addTab: aTab

self widgetDo: [ :w | w addTab: aTab buildWidget widget ]

should instead be:

addTab: aTab

self widgetDo: [ :w | w addTab: aTab ensureMorphicAdapter asWidget ]

but not sure about�
The problem is that original form works fine if adding static (on original initialisation)�
