Hi Jan,

This is because of a recursion bug in the tree presentation.

To address it when you create the tree presentation showing the productions add:

shouldValidate: false; allowsRecursiveSearch: false;

You should add this to all tree presentation that might display a recursive structure.

Cheers, Andrei

Hi, From time to time I see a bug in GLMTreeMorphNodeModel>>pathIn:

It happens like this:

1. PPSmalltalkGrammar new inspect.
2. Click to the tree view and do some clicking here and there, expanding

and collapsing nodes. 3) After some time, pharo freezes in a enldess recursion call. You can see it in the attached screenshot.

This behaviour is there for quite a time (at least half a year, as far as I remeber).

Cheers, Jan

PS: Where shall I report bugs like this? GoogleCode or FogBugz?
