Hello,

I am new to Sirius. I have looked through all the tutorials, examples and forums posts, but have not been able to solve my problem: Is there any detailed tutorial, that describes step by step how to make the creation tool for element based edges? All the tutorials only look at relation based edges.

What do I do wrong, when I have/do the following:

My model:
- classes: relationends, relation (each with variables: source (type ends), target (type ends), name (type String))
* i have a probelme with the creation of ELEMENT BASED RELATION.
this is my model
and properties of the relation.

Dear Mahdjoub,

In your case, you can not use Relation Based Edge mapping because you have an EClass relationship named Relation.
You must use Element Based Edge mapping, in the Domain Class field you have put the EClass named Relation.
In the Semantic Candidates Expression, you put the reference which allows to recover the relations.
After defining your mapping, you would associate a a creation tool for this mapping
