Description of problem:
As per the documentation
http://docs.jboss.org/drools/release/6.0.1.Final/drools-docs/html_single/index.html#d0e9051

drools is predefined variable, similar to kcontext which is available for usage - in RHS for example.

business-central is able to resolve kcontext but can't resolve drools variable,

Version-Release number of selected component (if applicable):
BPMS 6.0.3+rp#2

How reproducible:
always

Steps to Reproduce:
1. Create Guided Rule with drools variable used in RHS, i.e.:

1. | import java.lang.Number;
2. |
3. | rule "MyGuidedRule"
4. | dialect "mvel"
5. | when
6. | eval( true )
7. | then
8. | drools.setFocus( "whatever" );
9. | end

2. Save/validate/F5/re-open
3. Popup with following content is presented:

"ERROR: Could not find type for variable drools"

Actual results:
It is not possible to use drools variable in RHS in Guided Rule

Expected results:
It is possible to use drools variable in RHS in Guided Rule

Additional info:

The workaround is to use kcontext variable. Unfortunately, that's not possible due to
https://bugzilla.redhat.com/show_bug.cgi?id=1195241

So the workaround is to use plain DRL. Please have BZ-1195241 in mind when working on this.
