Dear list,
What it all boils down to is that I do not know which nodes will be
present at runtime. I only know that they will behave like their parent
node (the block) below. Does GMF support this? If so, can someone point
me to an example? Or should I go back to GEF? I did the QuantumDB
ER-diagram in GEF (code here: http://sourceforge.net/projects/quantum/),
where I add attributes at runtime for each column name.
Please advice.
Kind regards,
Jan

Dear list,
I am still using GMF. I modified the fillPalette function. It now adds
several entries with the same element type to the palette.
Whatever tool I select the same BlockCreateCommand is called. I
understand that. What I want to do now is to find out which tool was
invoked that caused the request to create the CreateCommand, if that
makes sense... I found this "Within your action find appropriate diagram
editor part and adapt it to GraphicalViewer; then
viewer.getEditDomain().getActiveTool()."
But it's not an action, and I think we are in the model, and not in the
edit parts.
Please help.
Kind regards,
Jan

Dear list,
I solved it by finding out about the palette in the
xxxSemanticEditPolicy and passed the tool name to a new constructor.
The tool name is
this.getHost().getViewer().getEditDomain().getPaletteViewer( ).getActiveTool().getLabel()
Then in doDefaultElementCreation I can match that name to the
configuration files and act accordingly.
Kind regards,
Jan
