AbstractEmfModel#store exception due to unmapped path [message #13728]

Hi,

When using AbstractEmfModel#store, I receive an IOException due to an
unmapped path.

I'm running Epsilon from source, and calling store from a runtime
workspace. Here's my code:

http://pastie.org/412896

save is the name of my project, and test.model is the resource that I
would like to be written.

I receive the following stack trace:

java.io.IOException: The path '/save/out.model' is unmapped
at
org.eclipse.emf.ecore.resource.impl.PlatformResourceURIHandl erImpl.createOutputStream(PlatformResourceURIHandlerImpl.jav a:424)
at
org.eclipse.emf.ecore.resource.impl.ExtensibleURIConverterIm pl.createOutputStream(ExtensibleURIConverterImpl.java:290)
at
org.eclipse.emf.ecore.resource.impl.ResourceImpl.save(Resour ceImpl.java:983)
at
org.eclipse.epsilon.emc.emf.AbstractEmfModel.store(AbstractE mfModel.java:464)
at save.Test.main(Test.java:16)

Is the filename passed to store wrong?

Cheers,
Louis.

Hi Louis,

I tried this code from a runtime workbench (a test button in a test
view) and it worked. On the other hand, when I tried it from a main
method it failed with the error you see too. The reason is that
"save/out.model" is resolved to "platform:/resource/save/out.model"
which when you are running a "main" is not mapped.

Cheers,
Dimitris

I see, that makes sense. I guess I'll see if I can find a way to map my
projects. (I'm not really running a main method; I'm running jUnit tests).

A somewhat related issue: I've also found that I can't create an
(Epsilon) EMF Model using the Epsilon perspective. I receive the
following exception.

It looks like Epsilon is using a mixture of platform and file URI. I'm
not sure which it should be using in this case. (/Users is a top-level
directory on my machine).

platform:/resource/Users/louis/Code/eclipse/workspaces/runti me-epsilon/gadin.actions.model/model/test.model

Adding the following before calling store works:

EcorePlugin.getPlatformResourceMap().put("save",
URI.createFileURI("/Users/louis/Code/eclipse/workspaces/runtime-epsilon/save/ "));

Cheers,
Louis.

Looks good! An alternative would be to use absolute file URIs e.g.
" file:/Users/louis/Code/eclipse/workspaces/runtime-epsilon/sa ve/out.model "

Hi Louis,

Thanks for reporting this. I've fixed it and committed the changes to
the SVN.

Cheers,
Dimitris
