Hi Stephan, I looked into the bug a bit and found something strange.... | m m2 | m := ColorPanel open. m2 := m submorphs third copy. m = m2 panel. "prints false; the panel is duplicated " ------------- add this method to DragWelL: veryDeepInner: deepCopier super veryDeepInner: deepCopier and it returns true. Another observation is that after all the text is lost, if you have a Playground that is effected and try to do something like: (ColorPanel allInstances size.) it raises an error 'MessageNotUnderstood: receiver of "style:" is nil' from "a GLMMorphicPharoPlaygroundRenderer actOnHighlightAndEvaluate: ann" Hope this helps Best regards, Henrik -----Original Message----- From: Pharo-dev [mailto:pharo-dev-bounces@lists.pharo.org] On Behalf Of Stephan Eggermont Sent: Friday, September 18, 2015 4:09 PM To: pharo-dev@lists.pharo.org Subject: [Pharo-dev] RubAbstractTextArea copying I'm trying to understand how to copy a rubric text morph.
