Validate two models of different metamodels [message #1781079]

Hi guys,

I have the following scenario:

Xtext generates automatically the AST of my DSL. In the IDerivedStateComputer
I transform this AST to another AST (derived AST from another metamodel) and put the derived AST to the XtextResource-Content-Slot1 with resource.contents.add(...).

Now I want to run the validator on the AST and on the derived AST. What is the best/cleanest way to do this?

Currently I override the register (EValidatorRegistrar registrar) and register the EPackage of the derived model.

Is there a better way? It would be nice to have one validator class for the AST and one for the derived AST.

PS: My application runs in the eclipse IDE

Many thanks :)

You just want to split the validators into 2 classes, one for your DSL metamodel and one for the derived AST?

Put it into a separate class and register it as an eager singleton binding as it is done for your DSLs validator.
