[XPAND] Can't find references to metamodel from template [message #764663] Mon, 12 December 2011 16:05 Go to next message

I have followed the "getting started" tutorial for creating xpand generator from here: I have created the ecore metamodel and generated java code. Then I loaded this project into the runtime and created Xpand project. When I get to the point of specifying the template I get an error "Can't find data:DataModel".

From another tutorials I found that I have to copy my .ecore model to the same src folder where I have my template. When I did that the error disappeared and it could find the model classes.
This is the first time I am using XPand and my question is do I have to always copy my .ecore file to the same folder as the template? Can I reference it differently?

Thanks in advance,

The EPackage of your metamodel must be known. This can be achieved by generating the EMF classes and use the org.eclipse.emf.ecore.generated_package extension point, e.g. like this:
   <extension point="org.eclipse.emf.ecore.generated_package">

Then your metamodel will be known in your UI.
