Help with Edge creation tool [message #1836052]

I'm a student using Sirius for a small research project.
I am trying to create the following diagram using Sirius Desktop, then I will need to deploy it using Sirius Web.
index.php/fa/39576/0/

This is my viewpoint(update it lacked the appropriate relations between concepts)
index.php/fa/39578/0/

Problem: Edge creation tool(connector) is not working, I can't connect the selected elements. I think it is might be because of my meta-model, but I don't know how to fix it.

I have also attached my .odesign file

Please note that I don't have experience with modeling, this is my first time using Sirius.

Indeed. The first problem is with your metamodel. It only includes composition relations, and misses relations between elements. Only after these are established, you can define presentations for them.
I highly recommend doing the basic family tutorial of Sirius (https://wiki.eclipse.org/Sirius/Tutorials/BasicFamily). Specifically, do the "Domain model tutorial" and then the "Starter tutorial". It should not take you more than half a day, and will allow you to do what you need.

I did go though BasicFamily and the Mindstorm tutorials, but I it's still not clear the steps required to manually create a generic edge between any two elements.
The example given https://wiki.eclipse.org/Sirius/Tutorials/AdvancedTutorial#Edge_Creation_Tool and the documentation https://www.eclipse.org/sirius/doc/specifier/diagrams/Diagrams.html#edge_tools did not help.

So, I created the simplest model that I could think of to create an edge:

Metamodel:
index.php/fa/39594/0/

ViewPoint, I'm not sure about the logic of edge creation:
index.php/fa/39595/0/

I don't really know what the value for "Target Finder Expression" should be?
index.php/fa/39596/0/

Set operation:
index.php/fa/39597/0/

Please let me know if you require more information

Thank you

Hello,

As pointed out by Avi, it is not clear one which semantic relation your connector will rely on?
The edge creation tool will allow to create an edge between two elements only if a consistent Edge Mapping exists between those elements. Before defining the edge creation tool, make sure that you are able to display the edge in your diagram.
If I take your second sample metamodel, it seems that you have defined an edge between an element of type A and an element of type B. Make sure that the relation"a" or "b "is properly set in your model and you should see the edge appears. In this case, the edge creation tool will create the semantic relation (by setting the "a" or "b" feature) and the edge will automatically be created according to the edge mapping.

Regards,

Florian

Thanks for the feedback Florian

I did that, but I had to create two "relation based edge"(and two "edge creation tool")
index.php/fa/39599/0/

But this is not what I wanted, Is it possible to simple do it with one?

Thanks for the feedback, I got most of model working.
I managed to get a single tool to represent my two relations(goal and goalRequirement), which works fine, but I'm not sure if that this the correct way to do it?

Hi Mike,

It seems that both goal and goalElements are references "many" and not container. The recommended name should be goals and goalRequirements.
The Set operation in the model will do a "ADD" on the corresponding list.

Are you creating an edge tool which will allows the user to clic on a source Experiment and an existing target GoalRequirement element ?
Is the tool intended to create a Goal element, store it in the model, add it to the source expriment goals and references the target (second clic) element as goalRequirement of the created Goal ?

Regards,

Thank Maxime.

I solved my problems after I read EMF and Sirius documentation, I refactored my model, added precondition and other advanced features.

As for the case of "single tool to represent my two relations(goal and goalRequirement)", I created an if statements to take care of each relationship(I think this was the recommend way to do it according to the documentation, I might be wrong though)
