Hi,

I have a scenario where in I want to filter the content assist proposals provide by Xtext. I have read post http://www.eclipse.org/forums/index.php/m/902814/ where they have told how we could in case of lookupCrossReference method. I wanted to know how to do if the method in AbstractDslProposalProvider internally calls completeRullCall method. What should be done in this case.

How could I filter the proposals in the above scenario?

Thanks for any help,
Latha

Hi,

what about simply overriding the method and do NOT call completeRullCall

Hi Christian,

If I just override the method then I myself have to build the proposals. But what I require is out of 10 proposals Xtext proposes, I want to remove only 2 of them and retain the remaining 8.

Is there anyway like the lookupCrossReference method overriding so that I just filter some of them?

Thanks,
Latha

here's a nice solution using Predicates:
