[Xtend] Autocomplete / code completion problems [message #543448]

Hello everybody,

I'm using Eclipse Helios. I've created a workflow that registers ecore-based metamodels using the registerEcoreFile function (that is, I'm not using registerGeneratedEPackage).

Now I'm about to create an Xtend transformation. I've imported all the (meta)metamodel namespaces which I would like to use.

import ecore;
import mymetamodel;

I noticed that the Xtend editor does not autocomplete any identifiers of mymetamodel in any context - i.e. I would expect the editor to suggest possible attributes and associations for any class/object while I'm typing. As far as I remember, this worked a year ago when I was using registerGeneratedEPackage (but maybe I was just dreaming back then ;-).

Any ideas how to turn on autocomplete if I want to stick to registerEcoreFile?

Hello Abdull,

the Editor do not care about the workflow configuration.
You have to configure the metamodel provider in the Xtend/Xpand properties.
If you use only emf then the EMF Metamodelcontributor should be selected (it is by default).

Please also ensure that the metamodels are on classpath.

I love this forum... codecompletion now works - thank you!

I've added the projects containing my metamodels using Project -> Properties -> Java Build Path -> Libraries tab -> Add Class Folder...

I guess it does not suffice to only have a .ecore file within the class folder to activate codecompletion. Probably, to activate codecompletion, a user always has to go through deriving from this .ecore file an EMF Generator Model, then "Generate Model Code", which results in generating Java files in the folder "src", packages "mymetamodel", "mymetamodel.impl", and "mymetamodel.util" ... right?

No the ecore is sufficient.
