[jboss-jira] [JBoss JIRA] Commented: (JBRULES-1613) In one special case, the naming of a Drools-Function causes an error

    [ http://jira.jboss.com/jira/browse/JBRULES-1613?page=comments#action_12415599 ] 
            
Brandon Chapman commented on JBRULES-1613:
------------------------------------------

I am having the same issue. In the below DRL method getRatingInfo is reported as undefined. If I change the rule to use the field name and let drools look up the getter, it does not find it. Changing the name of the object and getter corrects the issue.

rule "test table_106"
	
	when
		sub:SubscriberInfo(eval(getRatingInfo() != null), eval(balanceInfo != null))
	then
		System.out.println("Both are set");
end

> In one special case, the naming of two functions in the drl-File causes an error.
> Here my code (simplified):
>   
>   package....
>   import ....
>   rule ...
>     when
>       ....
>     then
>       checkHierachyInstance(...);
>   end
>   function void checkHierachyInstance(...)
>   {
>     checkHierachyInstanceRecursive(...);
>   }
>   function void checkHierachyInstanceRecursive(...)
>   {
>   }
> From this code i get the following runtime-error:
> [ checkHierachyInstance : Function Compilation error
> checkHierachyInstance (line:54): The method checkHierachyInstanceRecursive(Activity, SActivity, int, int) is undefined for the type CheckHierachyInstance ]
> Rule Compilation error :
> [Rule name=action_conditional_starttimereached, agendaGroup=MAIN, salience=0, no-loop=false]
>         action_conditional_starttimereached_5491408023587370397/Rule_action_conditional_starttimereached_0.java (15:857)
>  : The import action_conditional_starttimereached_5491408023587370397.CheckHierachyInstance cannot be resolved
>         action_conditional_starttimereached_5491408023587370397/Rule_action_conditional_starttimereached_0.java (20:1531
> ) : The method checkHierachyInstance(String, Consumer, Activity, SActivity, String) is undefined for the type Rule_actio
> n_conditional_starttimereached_0
> [ checkHierachyInstance : Function Compilation error
> checkHierachyInstance (line:54): The method checkHierachyInstanceRecursive(Activity, SActivity, int, int) is undefined for the type CheckHierachyInstance ]
> As far as i have found out, the error occurs ONLY if I append any character to the functionname "checkHierachyInstance", in my case the word "Recursive". It works if I use a completely different name instead of "checkHierachyInstanceRecursive" or exchange a character in "checkHierachyInstanceRecursive". For example I can use "function void myFunc(...)" or "function void checkHierachyInstancRecursive(...)" instead of "checkHierachyInstanceRecursive" .
> The only combination of function names i'm not allowed to use is checkHierachyInstance and checkHierachyInstanceXXX
