My DSL generates files of another DSL. At the moment these generated files of the otherDSL are not automatically validated after the generation.
(No warnings or errors in the problems view or package explorer). The file does have warnings and errors

I have the feeling i am misisng a simple flag i need to set to make this possible.

this is not possible,

an builder in eclipse does not see changes it did itself.

workaround: introduce another builder that touches the files built by the xtext builder so that the xtext builder will be called a second type.
