| Dynamically creating Objects with no graphical/tooling def. [message #174287] |

I am following mindmap and the BPMN editor examples to come up with a
similar editor. One thing I noticed in both these editors is that every
object/node has a associated graphical and a tooling definition. What if
the object is part of the domain model and has no graphical and a tooling
definition, and is supposed to get generated dynamically. To be more
specific, lets say in the BPMN editor, a "Process" gets generated
dynamically. By this I mean when I drop a Pool, a process instance gets
generated (with no graphical representation) in a Pool and I should be
able to drop other objects(tasks...) into the process. The serialization
of the model contains the process nested into the pool and graphical
objects nested in the process.
I have tried playing around with the the mapping definition model, but
couldn't achieve the above. I tried making changes in the BPMN editor, and
could reach to a point where I could find the process getting generated
dynamically and also nested in the pool, but the tasks that are dropped in
the pool/process are not nested in the process.
Looking forward for some pointers.

Hello neeraj,
From now it is posible to work with dynamic instances of EMF model in GMF,
but you still have to generate diagram code working with it, so I doubt your
use case is covered by current version of GMF. I suggest you to think about
static meta-model describing all your diagram elements.
