ResourceDescriptions in Validator [message #538122]

Hi!

I would need to get all the resources to do some complex checks in my JavaValidator.

However, the Injected IResourceDescriptions, although not null seem to be empty. I guess that the descriptions are not built yet at that point.

How might I get other resources in the validator to do my comparison?

It should be filled, in which context do you use IResourceDescriptions
and to what implmentation is it bound?

Coming back to this topic.

I'm using it in <MyDSL>JavaValidator (for a check on one of my rules) and I'm trying to iterate over getAllResourceDescriptions(). It's bound to org.eclipse.xtext.resource.impl.ResourceSetBasedResourceDesc riptions.

Now this normally works, however it doesn't work on a clean build (if I chose my project and run clean on it). In that case the getAllResourceDescriptions() won't return any resources.

This is kind of annoying because I get error markers (from Xtext Check (fast)) on files that are actually valid every time I clean or load a new project. And I can only remove them by re-triggering the validation (which only happens if I change something, anything, like adding whitespace, in the file).

Hello Filip,
a very similar question is in thread http://www.eclipse.org/forums/index.php?t=msg&goto=63311 8 and the solution is to use different IResourceDescriptions in some circumstances.
