Thanks for making the new case, I may resolve it soon.​

Thank you both... I'm getting burned from this Mooc. Reviewing slides all day long with Damien and Luc. Le 6/5/15 20:27, Nicolai Hess a écrit :

Hi All,

I had an issue - when I opened a Halo on a Spec tree node in the UI and select the menu Icon, I got a DNU message. However if I selected a normal Morph, the menu Icon worked fine.

I'm using Pharo 4.0 released version.

Fixed this by changing TreeModel>>iconFor to: iconFor: aNode ^ iconBlock value cull: aNode content*s* cull: aNode

Hi,

Thank you for the report (and the fix) I made a bugtracker entry:
