Hiding duplicate element [message #1802518]

Hello all,

I have one state machine with pseudo state, states, final state and transitions. On my diagram I have two final states one that comes from node that I created called "State" and one from "FinalState". I want to hide one Final State automatically (currently at the end of my machine I have two the same states)

How should I do it?

1. I have already searched forum and topcis connected to that problem. I have found this:
https://www.eclipse.org/forums/index.php/m/1771883/?srch=hide+diagram+element#msg_1771883
But find it unfriendly because I am still beginner. Where should I put that code and how to call it, how to add a changecontext operation in tool?

2. Second option that I have tried is Conditional Style where I would create special style for my FinalState that is also in metamodel part of states (uml.state) and delete FinalState (uml.finalstate). I don't know how should I write condition. I have tried aql:uml::FinalNode but it just selects all nodes...
Is this idea possible at all?

btw. I shouldn't change my metamodel.

I hope someone can help me. Thank you.

Hi,

The problem is related to your State node mapping defined in VSM.
Your associated Semantic Candidate expression should not return the semantic element that is considered as a final state.
So it is there that you should have the right AQL expression or Java service that return the collection of model elements that should be considered as State only. You have quick help next to mapping fields with ? icon to know what should be returned.

To do it in AQL I suggest that you read the documentation : https://www.eclipse.org/acceleo/documentation/aql.html#MigratingfromMTLqueries
If this is difficult for you, you can do it with pure JAVA code with a service: https://www.eclipse.org/sirius/doc/specifier/general/Writing_Queries.html#service_methods
