[rules-users] RE: 4.0.0-M2: RuleFlow "CannotResolveClassException"error

[Anstis, Michael (M.)]

I'll take a look at the new game of life implementation with a view to
shifting to rule flow - no promises though, I'm still new to this
"contributing thing".
 
Oh, you can call me Michael if you like too - I prefer to go by my first
name ;-)

	Anstis, Good work :) My next plan is to make a version of
conways game of life that uses ruleflow instead of the agenda groups.
check the new conways out, maybe you can do the implementation.
	
	I think the RFM file is just a data file for the GUI display,
not needed for runtime. Kris can you confirm?

		OK, I don't get the error if I use a RFM file instead of
a RF file - assuming this to be correct I've changed the wiki entry.

		I've also updated the wiki to show how to execute a
RuleFlow - not difficult now I know how, but since I spent a while
figuring it out thought it worth a mention.

		FYI, I have also successfully added the plugin to IBM
RAD7 and conducted a few preliminary checks (nice - I can emphasis the
"I" in IDE for my current project at work).

"CannotResolveClassException" error 

			Hi, 

			I added the Eclipse 4.0.0-M2 plugin and created
an example project; changing the class path to reference core-4.0.0-M2,
compiler-4.0.0-M2 and dependencies.

			I modified the example to include Ruleflow based
upon the wiki entry for 4.0.0-M2 and created a simple RuleFlow with two
RuleGroups ("one" and "two") one for each rule in the Sample.drl.

			I also modified the DRL to include Rule-Group
attributes ("one" and "two"). Unfortunately when running within Eclipse
I received the following error:-

	
com.thoughtworks.xstream.alias.CannotResolveClassException:
org.drools.eclipse.flow.ruleflow.core.RuleFlowProcessWrapper :
