locate elements into an EMF generated editor [message #778379]

Hi all,
I have a meta model from which I generate the typical emf model editor (from the genmodel file). In the meta model I have some meta classes that have references to other meta classes. When into the generated editor I select an element with references I can see into the Properties view the name of the referenced items...but I can't locate them, in the sense that I have to look for the referenced element on my own into the model.
I know that this is an already discussed argument but so far I can't be able to find a solution; I tried EMF Search version 0.10.0 with Helios, but it does not seem to work.
Is there any eclipse tool or subproject that can help me? or I have to do the work "by hand" with java code?

Thanks
Enrico

The property descriptor should scan the entire resource set looking for
instances that are compatible with the type of the reference... Of
course if the things aren't in the resource set, it won't find
anything. You have to use Load Resource... to find them.

It's not totally clear what your problem is. It's not finding things
that are there? You're wanting to find things that are in other
resources (which of course requires some mechanism that searches all or
some subset of all resources in the workspace).

My problem is not to find objects located in other models, my problem is to find objects referenced by some other objects of the same model.
I try to give you a better explanation of my case. I define a meta model MetaModelA with emf, then I generate the editor from the genmodel file using EMF fetures "Generete Model Code", "Generate Edit Code" and "Generate Editor Code"; with the newly created plugins I run a new instance of eclipse and I create a new model conforming to MetaModelA using the just generated editor. So far it is all ok, a task that I do many times. The question now is how given an object that has references to another object of the same model I can locate (and select) the referenced object into the editor.

A practical example:

MetaModelA:

MetaClassOne
{
...
}

MetaClassTwo
{
...
link1 : MetaClassOne; <---EReference
}

suppose that using tha EMF generated editor I build a model:

MetaClassOne object_one;

MetaClassTwo object_two
{
link1 = object_one;
}

I need to locate object_one into the editor, starting from the link1 reference.

Hi Enrico,

the properties view has a button "Locate Value" (near the minimize/maximize buttons)
that brings you to the referenced object.

Tim
