Hi,

i get the following error, when trying to execute my workflow directly
(i.e. <right click on the workflow> -> Run As -> MWE Workflow):

Exception in thread "main" java.lang.NoSuchFieldError: ruleMemo

I found the following solution:

http://www.eclipse.org/forums/index.php?t=msg&goto=51637 3&

This left me puzzled as I couldn't follow those steps.
I browsed the XText pages but the only version that can be installed is
the one from the download site. This version doesn't seem to include the
plug-ins mentioned in the solution above.
Also I couldn't find these plug-ins in the older version (1.0.0RC4
(2010/06/08)) here:

http://www.eclipse.org/modeling/tmf/downloads/

I can see that there is some trouble with the right ANTLR versions. Now,
how can i fix this dilemma?

I'm using Eclipse Galileo (3.5.2 Build id: 20100218-1602).

Thanks in advance,

Till

Hi,

you can download a eclipse 3.5 distro with Xtext, Xpand and MWE packaged from here: http://download.itemis.com/distros/
use it or extract the plugins you need from there.

Thanks for the link!

I tried extracting the plug-ins but messed something up big time.
Then starting freshly using a packaged distro from the link above and
loading some other plug-ins I need did the trick.

Cheers,
