Hi,
I'm looking for a way to apply some sort of dynamically created role to other elements within my diagram. As basic example, a root element tracks all Roles within the model and roles can be assigned to Entities. The challenge is that the user should be able to create arbitrary new roles or reuse previously created roles.
My thoughts/attempts:
1) Dynamically change the palette to have one item per existing role and somehow add new elements at runtime. From what I know, this is not possible with Sirius.
2) Display the list of roles contained in the root element and use the drag and drop feature to apply a role to the entity element. I got it working under the condition that the target element is a container itself.
Unfortunately, for reasons of representation, the entity element is not a regular container but should display the roles as bordered entities (which in itself works fine, too). Why is it not possible to drag an item to a non-container element? And how can I get a drag to a basic node working?
Am I missing some other possibility to implement this apply/assign behavior?
Greetings,
Christoph

If you want to create a new role you can add a Creation Tool [1] that
creates the new role in your model and set it on the selected Entity.
To set an existing role on a entity you can, for example, add a Generic
Tool that allow to select the Entity and then add a Select Model Element
Variable under a variable of the generic tool. It'll allow you to
select, through a selection wizard, the role you want to set on the
selected Entity.

Effectively, the drag'n drop tool works only if the mapping of the
source RepresentationElement (the element you want to drag, here the
node role) is the same of the mapping contained in the target
RepresentationElement (the Entity node contains only BorderedNode and
not Node)
Please, feel free to open a enhancement in Sirius Bugzilla :
https://bugs.eclipse.org/bugs/enter_bug.cgi?product=Sirius
Note that it works if you drag the role from the explorer.

Actually you can drop a Node1 with mapping NM1 into another Node2 if
mapping NM2 if:
* NM2 must contains a bordered node mapping BNM with same Domainclas
than NM1
* The drop tool must have NM1 *AND* BNM in its mapping
I think this behavior has not been explicity and voluntary designed as
it is today. It could be simplified and accordingly documented.
So it could be a good thing if you could open a bugzilla with your scenario

Thank you Laurent for the quick replies.
The option to use a selection wizard sounds like a sensible workaround, yet I prefer a drag and drop solution which seems more natural in the context of the overall tool.
Your comment on the RepresentationElement was the key to success. I wasn't aware that the source representation matters for the ability to drop an element. Therefore, changing the drag source representation to a bordered node, too, solved my issue.
Concerning today's comment, I can confirm that this works and looks even "nicer". But this is really a weird/unexpected behaviour which I will open a bugzilla for.
Edit: It should be noted that an additional effect of having NM1 *AND* BNM in the mapping is that it also enables BNM dragging from Node2 instance to Node2 instance. It's no problem for me and I appreciate the solution, just to keep in mind if someone else stumbles about it.
Best,
Christoph
