Indeed, TRMultiCompositeShape>>announcer should not be called. In your case, a multiCompositeShape was added in the Canvas, which should not happen. I fixed this, there was a bug when pushing back shapes.

Hi,

I think we have a problem with announcer from TRMultiCompositeShape. It is implemented as if it should not be called, but

TRCanvas>>shapeWithAction: eventClass forPositionInPixels: position

calls it.

So, we have a problem.

I observed the problem when creating edges with RTMondrianViewBuilder. For example:
view := RTMondrianViewBuilder new.
view shape label text: #asString.
view nodes: (1 to: 100).
view shape orthoHorizontalLine color: Color veryLightGray.
view edgesFrom: [:x | x // 10].
view horizontalTreeLayout layered.
view

And then click on an edge.
