schema validation during/before resource save. [message #416789]

Hi all,

i have 2 EMF models. M1 is my tool specfic model. M2 is schema derived.
Model is accessed / manipulated using M1 instances. Serialization of M1
uses schema of M2. i.e. model is serialized in M2 format. For this i am
doing a java based model transformation from M1 instance to M2 instance
refering an existing mapping.

I want to validate the M2 instance got by transformation against the
schema. Is there a possible way to do trigger schema based validations
before / during resource save ?

cheers,
Chetan Kumar

Hi Chetan,

We validate documents in a few places:
- Against the document used as input in the "Create Model"/"Create
Project" wizards
- On the validation action on generated editors
- When we open the Genmodel editor

Perhaps you could see how we do it and invoke the same code before
saving your resources. The validation action, for example, is located
in the "org.eclipse.emf.edit.ui" plugin
(org.eclipse.emf.edit.ui.action.ValidateAction).

Cheers,
Marcelo
