[jboss-jira] [JBoss JIRA] Created: (JBRULES-1012) Dot is removed while substituting variables with values in DSL
Dot is removed while substituting variables with values in DSL
--------------------------------------------------------------
Key: JBRULES-1012
URL: http://jira.jboss.com/jira/browse/JBRULES-1012
Project: JBoss Rules
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: Drl Parser/Builder
Affects Versions: 4.0.0.MR3
Environment: Windows XP, JDK 1.5.0_12
Reporter: Oleg Iavorskyi
Assigned To: Mark Proctor
There is DSL file with next content:
[when] There is a {type} named {name} = {name} : {type}()
[when] - {prop} is {val} = {prop} == {val}
And DRL which uses this DSL:
package prototype
import com.test.types.ClientServiceTypeType;
import com.test.ClientService;
expander ValidationCasesPrototype.dsl
rule "Bug with dot reduction"
when
There is a ClientService named cs
- type is ClientServiceTypeType.GOLD
then
# Then part
end
ClientServiceTypeType.GOLD is a public static final ClientServiceTypeType field.
When building package from this DRL file I've got next exception:
java.lang.RuntimeException: org.drools.rule.InvalidRulePackage: Unable to return
Declaration for identifier 'ClientServiceTypeTypeGOLD' : [Rule name=Bug with dot
reduction, agendaGroup=MAIN, salience=0, no-loop=false]

It seems that substitution for variables in DSL works incorrectly and simply ignores
".". Quick workaround is to use "\" before dot. In that case rules are
loaded correctly.
Same code worked in version 3.0.6.
