Using Sample Reflective Ecore Model Editor on our XMI files [message #426128]

When we save our models as XMI and then load them in the Sample Reflective
Ecore Model Editor it fails to find the ecore models.

We've set some options to get it to save the schema location but it only
populates it with the namespace uri not the file uri.

What is the trick to get this to work without having to edit each file?

Note we are not a plug in.

Interestingly, the meta model explorer finds all our models so if only it
could tell the editor about them we'd be set.

The schema location will be saved only if the ePackage.getNsURI() is not
the same as ePackage.eResource().getURI().

I'm not quite sure if you have a generated model or not. If you do, you
can specialize the XyzPackageImpl like this to ignore the uri, which by
default will be the nsURI and instead use some other physical location.

@Override
protected Resource createResource(String uri)
{
return super.createResource("<location>");
}

Thanks Ed

Adding the following to our root package did the trick.
@Override
protected Resource createResource(String uri)
{
return
super.createResource("platform:/resource/<path>/ourmodel.ecore ");
}

Thanks for all your help throughout the year. So far our EMF work has been
very positive. Its enabling us to take a step change improvement in how we
do things. Its a very impressive framework.

cheers

Andrew

Andrew,

I'm glad you like it. It's evolved over the last 6 years specifically
to address real world needs in a bottom up fashion. I'm always happy to
help people get past any roadblocks...
