[acceleo] eContainer() always return an invalid object [message #730974]

I know, I should not be using nightly version of acceleo. But maybe I have not understood exactly how to use .eContainer([filter]) operation.

Until now (before moving to 3.2-dev), I was using X.eContainer() to get the object containing X, possibly casting it in the process (X.eContainer(Y)). And it was working great.

But since the move to 3.2-dev, the eContainer() always returns an invalid object:
org.eclipse.emf.ecore.impl.DynamicEObjectImpl@128635 (eClass: org.eclipse.emf.ecore.impl.EClassImpl@292cb2 (name: OclInvalid_Class) (instanceClassName: null) (abstract: false, interface: false))

I can check in Eclipse using the debugger that my object does have the eContainer field correctly set.

If this is just me using unstable software, then I'll do my best to rollback.

If I can help debugging, I'm available!

Marc,

That's ... troublesome. We do not know of such a bug with the current master; and trying with the latest dev code, both "eContainer()" and "eContainer([filter])" work.

Could you provide us with a little more context on this? X.eContainer(Y) should always work, except if "X" is null or invalid; but that should not change with the latest version.

Laurent, as you are not aware of this bug, I'll first try to check and double check that the problem does not come from my setup

Thanks

Hi

Could be meta-model schizophrenia again. Is it possible that the same
model is available in two places (plugins, projects - not necessarily
open), or accessible by two different URI spellings? If so there could
be more than one "Y".

My setup maybe a bit strange as I'm developing a standalone compiler. I'm developing in eclipse using the plugin, but when executing, I'm using a bunch of jar files extracted from the 'plugins' directory. Until this 3.2.0 try , it was working nicely. Then, I was having a huge number of runtime exceptions (can't resolve URL, bad types, ...), so I decided to go back to my old 3.1.

Today, I updated again to 3.2.0.v20111007-0105, and my software is running fine (after having checked again that it was not working with the same set of 3.2 jars)

I guess there was something in the nightly version I was using that was not ok with my setup...

Hi,

We have indeed improved the stand alone use of Acceleo with the latest nightly builds of Acceleo 3.2.0.
