Hello all,

I discovered Richard Gronback's book "Eclipse Modeling Project" a few weeks ago and I am currently trying to implement the requirements diagram tool. I followed all the steps for the initial diagram (until page 114 ) and when I generate the code, the plugin project does get created with all the source code inside it but the classes RequirementGroup2CanonicalEditPolicy and RequirementGroupCanonicalEditPolicy contain compilation errors. In both of them, a method is called named "getRequirementGroup_200(2/3)SemanticChildren" but that doesn't exist in the RequirementsDiagramUpdater class. Beyond these only two errors the rest of the code is fine.
As my tests seem to prove, the problem comes from the top node references without containment feature. When I remove these, the generated code doesn't contain any error.
Did anyone face this problem already ? If so, how did you solve it ?

FYI I'm not using the amalgamation project. I just downloaded Eclipse Helios Modeling package and installed GMF.

Thank you and best regards.

Hello all,

I finally found out that my problem was caused by a bug in GMF tooling 2.3. It seems that on Helios release, there is no way to implement phantom nodes using tooling. I guess I'll just have to wait until there's a new GMF tooling release for Indigo and that it will correct the phantom node problem.
