I don't know if this helps but I encountered what seems like a similar problem and that is when TRRemoveCallback is attached to CompositeShape it is not called and I have to work around it by attaching the callback to the CompositeShape's subshape. Since RTLabelled uses it in such way I would suspect this to be the culprint.

This is no longer the case. :-( I tried to figure out how to fix it, but the RTEdge I get from the view does not seem to have any link to the label, so I cannot remove it by hand either. What can I do? BTW: RTArrowwedLine ? Should that not be RTArrowedLine ? More detailed code below: “construction" edge := (RTEdge from: efrom to: eto) model: trans name. arrow := RTArrowwedLine new color: trans color. arrow line width: 2. arrow head width: 2. arrow withOffsetIfMultiple. view add: ( (edge + arrow) @ (RTLabelled new color: trans color; view: view; offsetOnEdge: 0.3)) . “destruction” (view edgeFromModel: trans name) remove ---> Save our in-boxes! http://emailcharter.org <--- Johan Fabry - http://pleiad.cl/~jfabry PLEIAD lab - Computer Science Department (DCC) - University of Chile _______________________________________________ Moose-dev mailing list Moose-dev(a)iam.unibe.ch https://www.iam.unibe.ch/mailman/listinfo/moose-dev _______________________________________________ Moose-dev mailing list Moose-dev(a)iam.unibe.ch https://www.iam.unibe.ch/mailman/listinfo/moose-dev
