Problem saving representations in Sirius 4.0.0 using Xbase [message #1736903]

As opposed to Sirius 3.1.1 on Mars, saving a representation based on Xbase with Sirius 4.0.0 on Neon, an unsupported operation exception is generated. I'm using the same source project in both Sirius versions.

Installed the Eclipse Modeling Tools package for Neon and assured that the "Xtext Complete SDK" and the necessary Sirius components were installed from the Eclipse Neon Modeling Package Updates.

Save fails when referencing Jvm Types.

I noticed the following modification in the release notes of Sirius 4.0.0:

"The dependency from org.eclipse.sirius.common.xtext to the JDT plug-in org.eclipse.jdt.core is now optional. If you need the JDT Core in your environment, you will need to add the dependency explicitly. The Sirius specification environment ( org.eclipse.sirius.editor) still depends on PDE (and thus indirectly the JDT too)."

I'm uncertain if this may be the cause of the attached exception

Any suggestions are appreciated

Regards,
Eirik

At first glance I'd say it's unrelated. It looks like Sirius is trying
to save an EMF resource which comes from Xtext but which does not
implement the full contract of a Resource.

I have org.eclipse.xtext v2.10.0.v201605250459 in my context, which
provides an org.eclipse.xtext.common package, but I don't see the
org.eclipse.xtext.common.types subpackage or the TypeResource class
anywhere.

Can you tell which JAR (and which version) the TypeResource class comes
from? There *might* be some Xtext-specific test we can do on our side to
avoid saving unsaveable resources, but I'll need to find the actual code
before.

Pierre-Charles

Thanks for answering

I'm using the same version of org.eclipse.xtext (2.10.0.v201605250459) as you.

The TypeResource class resides in the org.eclipse.xtext.common.types (2.10.0.v201605250459) bundle in package org.eclipse.xtext.common.types.access

FYI, I'm successfully saving the same Xbase model representation with Sirius 3.1.1 in the Mars version.

Eirik

It looks like this change:

https://git.eclipse.org/r/#/c/64483/

could be the culprit. It assumes resources which are modified but should
not be saved will have the URIConverter.ATTRIBUTE_READ_ONLY attribute set.

Are you in a context where you can easily confirm by reverting the
single-line change in IsModifiedSavingPolicy and re-testing your
scenario? If so, and if indeed this is the changed that caused the
regression, please open a bugzilla.

Thanks.

Thanks again

I will make it a try,
Where is the best place to download the Sirius source?
Obeo Designer 9.0 or github?

The official source repository is available at
https://git.eclipse.org/c/sirius/org.eclipse.sirius.git, but there is a
simpler solution: if you have in your workspace a plug-in which depends
on org.eclipse.sirius (where IsModifiedSavingPolicy is defined), find
the org.eclipse.sirius JAR in your project's "Plug-In Dependencies" in
the Package Explorer, and from the context menu choose "Import from
Repository...". It will start a wizard which will automatically clone
from the official sources and import the sources for that plug-in in
your workspace.

Thanks for taking the time to confirm and report the bugzilla.
