Hi, I am only guessing right now but my guess is that when the connectors is trying to compute the points to make the curly it might use a global point for reference (the mouse event point for example) without a #globalToLocalPoint: translation to obtain a point in the diagram pasteUpMorph coordinate system.

Ned, would you point me where in your NCConnectorMorph code is this curly connectors logic, so I can check it? Thanks

regards, Hernán

There's a problem when you try to connect a connector to the same item it originates from in a Jacaranda Diagram. This is the sort of thing you might do in a state diagram to indicate a self-transition. The connector ends up pointing more or less at infinity in some seemingly random direction. Oddly if I just grab the item (say a state) out of the Jacaranda diagram and drop it in the world I can create a self-transition just fine. Drag the state back in, edit the self-transition connector a little bit and it's OK.

Hi list! Sorry for the big delay on the release of this fix but I didn't have enough time for squeak until the day before yesterday.

What this change set will do is insert the following in: NCConnectorMorph>>fixDegenerateLine

"p1 and p2 are in SourceMorph coordinate system" transform := owner transformFromWorld composedWithLocal: (self sourceMorph transformFromWorld inverseTransformation). p1 := transform globalPointToLocal: p1. p2 := transform globalPointToLocal: p2.

The thing happening was that the inner vertexes of the line were computed on the connected shape coordinate system while the outer vertexes in the world's one.

from the preamble: "This change set will fix the problem in connectors when you connect both ends of a NCConnectorMorph to the same shape and the morph owner isn't the world."

Ned, Should I add this .cs to Jacaranda or you are gonna add it in Connectors?

Thanks.

Regards, Hernán
