[news.eclipse.modeling.gmt.amw] Re: feature e does not exist on

[kornev <y.kornev@xxxxxxxxx>]

Hi Marcos,
i am using the ATL launch configuration

structurebase ->MOF
IN->AMW
interbase ->MOF
advice ->MOF

structurebase ->structureBase.ecore
interbase ->interBase.ecore
advice ->interaction.ecore
MOF ->#EMF
IN ->test.ecore
AMW ->w_model.ecore

so, structurebase, interbase and advice are metamodels that conform to Ecore

best regards,
Yuri
