"Save as" with multiple file formats [message #640834]

Howdy,

I have a data model that can be persisted in two different file formats - so far so good. At least for now, the two formats have different file extensions. So I simply created two extensions of org.eclipse.emf.ecore.extension_parser - so far so good. I also registered the same editor for both file extensions - this works.

My problem: I was hoping that I could switch from one file format to the other by opening the model in the editor, and then simply doing a "Save as" operation with the other file extension. But this doesn't work - it simply writes the model in the original format.

Before I start hacking something together I wanted to ask here for the "right" way to address this issue.

Thanks,

- Michael

You can look at EcoreEditor to see how it deals with saves for *.emof
verses *.ecore, which represent two different formats for saving Ecore
instances.

Excellent - this was exactly what I was looking for. It just took me a few minutes to implement, and it works as intended. Thanks a lot.
