[xpand] how to list elements of a containment reference (Ecore model) [message #638793]

Hello!

This is a Xpand newbie question...
I have an ECore model where the EClass API has a containment reference to EClass Module.
Therefore there is a method getModules() in the generated package for API (that returns a EList<Module>)

In my Xpand template I have the following:
«DEFINE package FOR API»
«FOREACH this.getModules() AS m-»
«EXPAND template::ModuleHPP::hpp FOR m»
«ENDFOREACH-»
«ENDDEFINE»

But I get the exception: EvaluationException : Couldn't find operation 'getModules()' for model::impl::APIImpl

What is the correct way of looping over the elements contained in the API object?

Thanks!
Benjamin

Hello Benjamin,

just writing this.modules should do the trick.
Btw. Xpand Editor (Add Xpand/Xtend Nature and Configure it properly) should help you with content assist.
