             Summary: Error to declare Map/List with generics when having a modify() on RHS
                 Key: DROOLS-493
                 URL: https://issues.jboss.org/browse/DROOLS-493
             Project: Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
         Environment: * OS: Mac OS X 10.9.2
* Java SE 1.7    
* Drools Runtime 6.1.0-Final   
            Reporter: Jinghai Rao
            Assignee: Mark Proctor


For the following rule

-----------------------------
package com.sample
 
import java.util.Map;
import java.util.HashMap;

declare TestFact
    @propertyReactive
    data : String
end

rule "Test Rule"
    when
        $fact : TestFact()
    then
        Map<String,String> a = new HashMap<String,String>();
        modify ($fact) {setData("0")}
end
------------------------

We get the following exception:

java.lang.RuntimeException: Error while creating KieBase[Message [id=1, level=ERROR, path=rules/Sample.drl, line=11, column=0
   text=Unable to resolve type Map<String,String>:
Unable to find class 'Map<String,String>']]
	at org.drools.compiler.kie.builder.impl.KieContainerImpl.getKieBase(KieContainerImpl.java:260)
	at org.drools.compiler.kie.builder.impl.KieContainerImpl.newKieSession(KieContainerImpl.java:400)
	at org.drools.compiler.kie.builder.impl.KieContainerImpl.newKieSession(KieContainerImpl.java:375)
	at com.sample.DroolsTest.main(DroolsTest.java:17)


If we remove the generics, or not using modify(), this has no error.
