Copy Gliffy diagram into Confluence, the hard way

Today I accidentally created a Gliffy diagram outside my Confluence user account and wanted to copy that into Confluence.

This should, in theory, be a simple task: Export the diagram as a *.gliffy file, import in Confluence. DONE!

Hahahaha. Yeah.

You didn't think it would be that easy, did you?

Confluence failed me multiple times for this method, so I had to work around, and here is how:

1. Right-click in your Gliffy diagram and select "View diagram source". Copy the content of the popup.
2. Create a new file on your computer, named something.gliffy and paste the diagram source in here.
3. Import that file into Confluence.

Phew. Weird, isn't it?
