Description of problem:
The guided rule definitions, that are part of jboss-bpm-example (Big App) should be reviewed. It should be possible to open each of them in Guider Rule Editor (GRE) and also to validate them successfully. However that is not the case. Currently there are the following issues:


1. Jumbo Mortgage - possible to open, but does not validate in GRE.
seems like the statement is not parsed correctly by the editor: application.setApr( application.getApr() + 0.5 );
--> We get the error:

Unable to Analyse Expression System.out.println("Executed Rule: " + drools.getRule().getName() ); application.setApr( );: [Error: unable to resolve method using strict-mode: com.redhat.bpms.examples.mortgage.Application.setApr()] [Near : {... application.setApr( ); ....}] ^ [Line: 3, Column: 0]


2. Rules 'Low down payment before appraisal' and 'Low down payment based on appaisal' do not even open in the editor

3. Rule 'Validate down payment' - rule is not parset correctly by GRE as you can see by checking the source tab. I believe it is caused by the syntax:
 Application( downPayment < 0  || > property.price ) which based on latest info from engineering might no longer be supported.

4. Rule 'Validate SSN' - same issue as in 3 (rule not parsed by GRE editor)


Version-Release number of selected component (if applicable):
BPMS 6.0.0 ER5

How reproducible:
Always

Steps to Reproduce:
1. Install the jboss-bpm-example (Big App)
2. In project explorer navigate to MortgageDemo application and try to open each of the guider rules and try to validate each of them

Actual results:
See details above -
1 rules does not validate (seems like it's not parsed correctly)
2 rules cannot be opened
2 rules are parsed incorrectly - they are not fully read in the G.R.Editor (recommendation do not use shorthand syntax for comparions)

Expected results:
It should be possible to open all rules and all of them should pass validation.
