Description Denes Harmath CLA 2015-02-27 10:17:21 EST

Minimal example metamodel

Given an example metamodel (attached), if we create the following query definition:

import "http://foo"
import "http://www.eclipse.org/emf/2002/Ecore"

@Surrogate(feature = "derived")
pattern fooDerived(foo: Foo, value: EString) {
	Foo.notDerived(foo, notDerived);
	value == eval(notDerived.toUpperCase);
}

Pattern fooDerived has an error:
Error building generic query specification

The Error Log contains multiple instances of the following exception for multiple fragments in the query definition resource:
org.eclipse.xtext.xbase.resource.BatchLinkableResource  - Don't resolve expressions during indexing!

Comment 2 Denes Harmath CLA 2015-02-27 10:20:36 EST 
Strangely, the error does not occur on the first save, just afterwards.

Comment 4 Zoltan Ujhelyi CLA 2015-02-27 13:11:46 EST 
Should be fixed in master. I turned off the generic loading support for surrogates entirely; it caused lots of nasty side-effects.
Comment 5 Denes Harmath CLA 2015-03-02 05:22:51 EST 
The fix is confirmed to work.
Comment 6 Zoltan Ujhelyi CLA 2015-03-02 17:11:32 EST 
As comment #5 described, this issue is already fixed.
