UML Model Editor/ Importing [message #626093] Wed, 27 February 2008 00:49

Originally posted by: pfuriani.uci.edu

When my plugin is running as an Eclipse Application, I have problems with
the UML Editor. If I create the uml model inside the running eclipse
environment, then the editor loads fine, but when I try to bring in a .uml
or .xmi file and open it with the UML editor, then eclipse gives errors and
can't open the UML editor because it says an "assertion failed". Is the UML
editor not able to import when being run from an Eclipse Application
instance that is being run from the main Eclipse Application?

My ultimate goal here is to find a way to use the UML Model Editor's process
of parsing an XMI file into whatever form it stores the data it in memory so
that I don't have to write my own XMI parser. I think it stores it as a
GenModel, but I'm not sure yet. If so, then my hope is that getting the UML
information from the GenModel (or whatever its stored as) would be much
easier than writing an XMI parser from scratch. Do you have any idea of how
I could use UML2 to do the XMI parsing and then get a reference to the
object its stored as? Or if you could let me know the class that does the
parsing of the XMI file and storage into an Object that would also be
helpful. Thank you.

Here is the stacktrace I get when I try to import when running my plugin as
an Eclipse Application:
