I'm using exactly what the documentation
(http://wiki.eclipse.org/Welcome_STEM_Developers) has you use... on the
Wiki pages for STEM it says to use Eclipse 3.3 and the update manager -
which gives you EMF 2.3.1 and 2.3.2 files.
I attempted to download EMF 2.4 and install that once I found out what the
source of my errors were, but that only resulted in catastrophe since EMF
2.4 and Eclipse 3.3 don't play nice.
I was actually just about to come on here and ask if STEM worked with
Eclipse 3.4, since installing that is the only other option I can think
of.
So, it would appear that the current source is not in line with the
documentation...
I'll try and install Eclipse 3.4 with EMF 2.4 and see if that fixes the
errors.
