|Re: [henshin-user] delete node problem|
Sorry bad-wording by the code I just meant running the transformation just by 'apply transformation' on the files. I just want it to find a match.
I cannot anyhow specify that containment edge between EReference and EPackage in the Henshin editor, it doesnt let me connect them. And if that was the problem then why does it find a match in the ecore file but not in the behavior file? Because my main problem is that it works/finds a match when run on the server2.ecore file but when adding a 'top layer' to run it on server3.behavior :Behavior -> :MetamodelGD - > :PackageGD it doesn't find a match anymore but these only provide the reference to the ecore file so it doesn't make any sense.

To understand why the rule cannot be applied, it's crucial to know that Henshin aims to ensure that output models of a transformation are well-formed: in particular, it aims to ensure that rule applications never leave behind "dangling edges". In your example rule, since you do not specify the deletion of the containment edge between the :EPackage and the :EReference, this edge would be left behind as dangling, so Henshin won't apply the rule.
To make the rule applicable, it should be sufficient to specify the deletion of the aforementioned containment edge. (Another option is to the set the "checkDangling" attribute in the rule to "false", however, in this case, you may lose well-formedness guarantees.)
I can't find the code you mention in these statements. The zip file only contains the models and Henshin files.
