As title says, whenever I select Connection the getSelection() method is called. Looks like it's called when ShapeEditPart is selected which is not ancestor of ConnectionEditPart. Can anyone suggest what am I are doing wrong?

Alex,

I don't think you are doing anything wrong. The getSelection method was introduced to change what is being selected in the tool behavior provider, e.g. for shapes that have an invisible outer shape. This is done only for shapes not for connections.

What are you trying to achive in the getSelection method for the connection?

Micheal,

My issue is that when I have two shapes with a connection between them, and I select all 3 objects, only the shapes get selected and not the connection. Indeed, when I comment out getSelection() method nothing changes.

Alex,

actually that is the expected behavior when you select a group of shapes and connections in the editor. Why do you expect the connection to be selected as well.

Well I don't expect it to be selected visually, but when I am in getSelection() method if I have two PE's with Connection between them, all I get are the two PE's as part of selection. I want to implement copy/paste so I need to figure out manually which connections are involved so that they can be copied as well. I guess I assumed that this method would give me all selected PE's.

What Graphiti offers here is directly based on GEF; the shapes are the objects that are selected. Connections are dependend in a sense that they cannot exist without a shape they are being connected to.

Since the expectations differ on connection handling between different tools, the standard behavior is not to provide connections in the selection. For copy & paste that means that the tool is responsible for adding the connections it would need to copy.
