How to access EMF objects into a transaction [message #1062881]

Hi all.

Is there a way to execute some operations on EMF objects into a transaction?

I'm using Xtext and I worry that the operations that I do on EMF objects (for scoping, labeling, and so on) are interleaved with those of the reconciler, so I obtain some org.eclipse.emf.common.util.BasicEList$BasicIndexOutOfBoundsException.

My fear is that the reconciler refreshes the model in another thread and so while I try to access it, the old model does not exist anymore.

How can I execute my operations on EMF model into an atomic transaction?

Thanks in advance,
Marco

Marco,

No, EMF provides no such functionality directly.
