Postorder traversal of AST during validation. [message #759799]

Xtext validation checks are executed in preorder traversal of the AST. This is quite inconvenient in particular for expressions where one often wants postorder (subexpressions validated first). Is it possible to configure the traversal that is used during validation?

Thanks,
Victor

Hi Victor,

you may want to bind your own CancellableDiagnostician and customize the
model traversal there.

Regards,
Sebastian
