Teneo resources and the EMF Validation framework do not properly work together [message #116142]

Hi!

I'm trying to use the EMF Validation framework (not to be confused with the
EValidator API) together with an EMF editor based on JPOXResource. The
editor works fine, I can run the validation and I even get results in the
form of a popup window. Problem marker generation (with
EclipseResourcesUtil used by ValidateAction) however, is broken because
calls to IFile EditUIMarkerHelper::getFile(Object datum) return null for
JPOXResource objects. The getFile method propagates to
MarkerHelper::getFile(URI uri)) which checks if the URI is a platform URI
and returns null if it is not.
Are there any workarounds known for this problem?

Cheers,
Florian

Hi Florian,
With me (Eclipse 3.4) the MarkerHelper.getFile method is like this:
protected IFile getFile(Object datum)
{
if (datum instanceof IFileEditorInput)
{
return ((IFileEditorInput)datum).getFile();
}
else if (datum instanceof IFile)
{
return (IFile)datum;
}
else if (datum instanceof Diagnostic)
{
return getFile((Diagnostic)datum);
}
return null;
}

what type is the datum object?

For the rest I do not know that much about the validation framework. Questions regarding validation
are answered on the EMF newsgroup which I added to this post.

btw, I had the same type of issues while integrating teneo and gmf. To solve that I had to change
part of the gmf logic. With gmf this was easy as I could do this in the generated code.

The method which is called is getFile(URI), getFile(Object) is overridden by
EditUIMarkerHelper. After digging a bit deeper, it became clear that the
Eclipse Marker support is based on IResource objects. Which leads me to the
question: Is there an adapter (or something else) available mapping
JPOXResource / StoreResource to IResource?

I have found a references here:
http://dev.eclipse.org/newslists/news.eclipse.platform/msg57 934.html
but unfortunately it does not provide a solution. The original thread on the
eclipse.tools.emf newsgroup is unfortunately not accessible anymore:
http://dev.eclipse.org/mhonarc/newsLists/news.eclipse.tools. emf/2006/Aug/index.php

Florian,

It's certainly potentially possible that the URI scheme Teneo uses for
accessing resources could be registered with Eclipse's EFS
(EclipseFileSystem) so that the resources could be surfaced as
IResources in the workspace. But I don't think Martin has done anything
like that.

The EMF newsgroup is definitely still accessible since I'm answering
your question from that newsgroup.

Yes as Ed says I have not done anything with EFS. I found this article which gives a nice overview
of what is required to implement an efs:
http://www.eclipsezone.com/articles/efs/

It is an interesting topic although I wonder how the efs can be mapped to a relational db (and vice
versa). Florian, can you enter a bugzilla for this?
As my time is limited it can take a while before this is done. Contributions regarding this topic
are ofcourse more then welcome!

btw, afaics adding efs support to Teneo does not solve the fact that the uri is not a platform uri
and that MarkerHelper returns null.

I just found a workaround using the ejdo resource. I simply create a project
in the workspace, calculate the file url for the ejdo file I want to use
(it's stored in a plugin) using FileLocator, create a new file link to the
ejdo file within the new project and use the project url of the file link
to open the editor. Problem solved. shall I document the workaround
somewhere?

Cheers,
Florian

Yes it would be great if you can write up a small page with the problem description and the solution
and then send it to me. I will then add it to the docs.

Thanks!
