Get selected element in a diagram/table [message #1695832]

Hello,

I would like to add an element to an element in the diagram. So, I would then need to find the selected element in the diagram and change the context with it. How is it possible to find the selected element in the diagram so that I can change the context with it? Also, is there a way to do it also for a table? How can I get the selected element in a table?

Thanks

Hello,

If you want to add an element B to an element A on a diagram, you will
need a node creation tool [1] or a container creation tool[2], depending
on the mapping element to add. Both of these tools provide the variable
"container" that refers to the semantic element you selected (therefore
element A). The expression in your "Change Context" operation will be
"[container/]" or "var:container".

Regards,
Steve
