Questions on the org.eclipse.core.filebuffers.documentCreation extension point [message #213324]

Greetings,

(this is about doing Plugin development for 3.0M7)

I'm curious about how this extension point is meant to be used. The
documentation on it is currently a little spare.

My question is this: what is supposed to happen if two plugins claim
the same file extension? I'm working on a specialized subclass of
CompilationUnitEditor and I need my specialized Document class to
back the editor.

Experimenting around, I've found that my DocumentFactory "wins" if no
editors were opened during workbench startup, but the JDT
JavaDocumentFactory "wins" if there were some (either my Editor or the
JDT CompilationUnitEditor).

Any clarification on what's supposed to happen would be very helpful.

I'm also open to other suggestions on how to get the framework to create
and use my own Document objects for local .java files.

Thanks,
mike

See org.eclipse.core.internal.filebuffers.ExtensionsRegistry.

It does not look like a particular order is ensured, but always the
first element from a HashMap is returned. If this is a problem for you,
you should probably file a bug report against platform-text.

Right.

I think I will. The behavior should at least be defined or documented.
