In the change log for Xtext 2.8.0, a new feature called "storable resources" is mentioned. Is there some documentation or example use available?

Hi,

i dont know any example (yes xbase stuff indirectly uses it anyway) but it should be fine to bind StorageAwareResource and StorageAwareResourceDescriptionManager

Hi Christian,

thanks for your quick answer. It did not work completely - AbstractFileSystemAccess2 also has to be bound in the UI module.

Hoever, there is another problem. In my setting, there are 2 Xtext-based languages. Language B imports objects defined in language A (using the importURI mechanism).

When the builder for language B runs, I get Guice errors:

com.google.inject.ProvisionException: Guice provision errors:

1) No implementation for org.eclipse.xtext.generator.AbstractFileSystemAccess2 was bound.
while locating com.google.inject.Provider<org.eclipse.xtext.generator.AbstractFileSystemAccess2>
for field at org.eclipse.xtext.resource.persistence.ResourceStorageFacade.fileSystemAccessProvider(Unknown Source)
at org.eclipse.xtext.service.MethodBasedModule.configure(MethodBasedModule.java:56)
...

However, defined the following binding in the UI modules of both languages:

public Class<? extends AbstractFileSystemAccess2> bindAbstractFileSystemAccess2() {
return EclipseResourceFileSystemAccess2.class;
}

I am wondering what is missing here.

Best regards,

Tim

Hmm i have no idea for that. i cannot reproduce it locally (with a simple setup). do you have a full trace for the error? maybe it is a bug. maybe you have some other configs that cause the problem.

Hi Christian,

I think our own BuilderParticipant implementation caused the problem. I had to define a binding for AbstractFileSystemAccess2 in the runtime modules of our languages. The binding in the UI module which I mentioned before was not needed.

Thanks a lot for your help!

Best regards,

Tim
