[jboss-jira] [JBoss JIRA] Commented: (JBRULES-1439) Property Name inconsistent on RHS

greywind commented on JBRULES-1439:
-----------------------------------

Just one more question. That means that in a Java consequence we cannot use Java Bean Property type Accessors. MVEL does allow just that. Would it be a valid feature enhancement to have Java Bean Property Accessors in the Java consequence?

>          Issue Type: Bug
>      Security Level: Public(Everyone can see) 
>          Components: Drl Parser/Builder
>    Affects Versions: 4.0.4

> I apologize right from the start if this is a know thing, but I couldn't find it in the Documentation or the mailing Lists:
> 	public class Settlement
> 	{
> 		public String InstrumentType,InstrumentName;
> 		public String getInstrumentType() {
> 			return InstrumentType;
> 		}
> 		public void setInstrumentType(String instrumentType) {
> 			InstrumentType = instrumentType;
> 		}
> 		public String getInstrumentName() {
> 			return InstrumentName;
> 		}
> 		public void setInstrumentName(String instrumentName) {
> 			InstrumentName = instrumentName;
> 		}
> 	}
> The following Role leads to an error during compilation as the Property instrumentName can not be found on the RHS. in the LHS it is found:
> rule "TestEntity"
> //dialect "mvel"
> 	when
> 		$s : Settlement(instrumentType == "BOND", name : instrumentName)
> 		
> 		#conditions
> 	then 
> 		System.out.println("Found: " + $s.instrumentName);
> end
> It seems that in the java dialect the LHS follows java bean notation (property start with lower case) on the RHS not. I have to specify the property with UpperCamelCase on RHS to make it work:
> rule "TestEntity"
> //dialect "mvel"
> 	when
> 		$s : Settlement(instrumentType == "BOND", name : instrumentName)
> 		
> 		#conditions
> 	then 
> 		System.out.println("Found: " + $s.InstrumentName);
> end
> the MVEL dialect on the other hand handles this as expected. the property is LowerCamelCase on both sides:
> rule "TestEntity"
> dialect "mvel"
> 	when
> 		$s : Settlement(instrumentType == "BOND", name : instrumentName)
> 		
> 		#conditions
> 	then 
> 		System.out.println("Found: " + $s.instrumentName);
> end
> I would expect that the java dialect should work the same way here, should it not?
