I cannot reproduce this problem :). Are you sure that you selected the item before hand?

In any case, take a look at the code examples from MooseBrowsers. For example: MooseBrowsers>>navigationBrowserOn: scopeSelector ... actions: [ :tree | tree selection mooseInterestingEntity mooseFinderActions ] Cheers, Doru On Thu, May 27, 2010 at 11:35 AM, Simon Denier <Simon.Denier(a)inria.fr&gt; wrote: I'm trying to set some actions on items in a glamour tree presentation, say: actions: [:tree | tree selection xMenuItems ] But #selection called on the widget returns nil.

Yes, I am interested. I never encountered this case. "tree selection" gets the result from the #selection port. Please describe the scenario.

Ahh, the problem is that you also specify the #send: clause, which is a post transformation that affects the value of the #selection port. Given that sometimes this value is nil, you get nil :).
