Description Stéphane Thibaudeau CLA 2015-09-02 09:47:42 EDT

Example project

Given an ecore model containing 3 EPackages :

A <>-- B <>-- C
A class diagram is defined on each package.
B has been controlled (only semantic).

(provided project corresponds to this starting state).

When I try to control the C package, a NullPointerException occurs and no file has been created.


Steps to reproduce :
1) import provided project
2) try to control "C" (both semantic and graphics) => NullPointerException
Comment 1 Stéphane Thibaudeau CLA 2015-09-02 10:07:16 EDT 
The problem seems to be with SiriusUncontrolCommand.

getParentAirdResource() calls getAirdResourceWithAnalysisOn(EObject) giving the "B" package as a parameter. This method then returns null.
Comment 2 Maxime Porhel CLA 2015-09-03 08:50:47 EDT 
The getAirdResourceWithAnalysisOn(EObject) should never return null: it should recursively fall back to the parent fragment. In the worst case it will return the main session resource found from the resource of the semantic root.
