Hi all,
I have a question about link and link constraints.
I want to create a link which have multiple uses:
For example :
A<>------------B (A aggregates B) and
A<>------------C (A aggregates C)
Now my RCP application have 4 Creational Tools in the toolbar (Create Node A
, Create Node B , Create Link from A to B and Create Link from A to C). What
I want is to use just one link type to connect A with B and A with C, so in
the toolbar I will have just 3 creational tools.Also if I have a node D I
don't want to allow connection beetwen A and D....because A doesn't
aggregates D. How can I do that?

Hi, I've recently done a very simular thing!
Inorder to reduce the number of tools in my palette I have placed multiple
connections into one tool!
The way to do this is very simple, create your graphical def same as you
would for multuiple tools, create a single tool in your tooling def, then
in your mapping model simply add a link mapping for each link and assign
them all to there indervidual graphical representation(diagram link),
assing there connection type(target feature), then assign them all to the
same tool
However I currently face a problem with this, when you then draw a tool a
menu is displayed inorder for you to select the connection type you want,
but all the names are set to 'create undefined'
...Hope this helps, if you chose to use this method and find a solution to
the problem above it would be great if you could let me know!
