Can't find genClass for class 'DocumentRoot' in package TimeModel [message #83025]

Hi folks,

I am taking my very first steps with GMF, developing a sample model as
attached. When I try to "Create generator model" from the gmfmap editor I
get the following error message (copied from the log):

=============================
eclipse.buildId=M20060921-0945
java.version=1.5.0_06
java.vendor=Sun Microsystems Inc.
BootLoader constants: OS=win32, ARCH=x86, WS=win32, NL=de_DE
Command-line arguments: -data D:\Projekt\RTP\ws-gmf-dev -os win32 -ws
win32 -arch x86

Error

An internal error occurred during: "Create generator model...".

Can anybody give me a clue what I have missed?
Thanks,

Norbert

Hi Norbert,

I had a problem similar to yours which I've fixed by starting Eclipse with
an additional parameter: -vmargs -XX:MaxPermSize=256m.
I hope this may help you.

nah, in my case somehow the .genmodel was out of sync with the .ecore, hence
some classes were not found.

Thanks all the same
