How can I change the diagrams ID?
I first designed quite many diagrams all separately (unfortunately). now I discovered, that I should have designed them all in the same file.
Then I exported them all into separate XPDL-Files in order to import them again in one single new file. That worked fine for many of them, but for some it doesn't... Attemting to import them, I get an error-message saying
"A diagram with the same Id already exists"
Can I change this ominous "diagram Id" anywhere? Where?
If not: Can I workaroud it and import it anyway?
