[drools-user] Problems with Array-Parameter in functions

[Kihm, Christian]

Hi,

 

we plan to migrate our rule-base vom drools 2.5 to jbossrules. But we
have many Problems to get it run. If there is for example a function
with an array parameter like this:

 

function void yourFunction(String[] args) {

      /* code goes here*/

}

 

Then the excecution ends with following error:

 

org.drools.rule.InvalidRulePackage: unknown:5:45 Unexpected token '['

unknown:5:45 Unexpected token '['

 

      at org.drools.rule.Package.checkValidity(Package.java:378)

      at
org.drools.reteoo.RuleBaseImpl.addPackage(RuleBaseImpl.java:303)

      at com.sample.DroolsTest.readRule(DroolsTest.java:77)

      at com.sample.DroolsTest.main(DroolsTest.java:23)

 

 

For tests we have to some boxing/outboxing with the array parameter like
this:

 

function void yourFunction (List argsM){

      String[] args = (String[])argsM.toArray(new String[argsM.size()]);

/* code goes here*/

}

 

 

rule "argTest"

 

      salience 11

      no-loop true

 

      when        

            eval( yourFunction(Arrays.asList(new String[] {"1", "2",
"6"})) )

      then

            System.out.println("it works");

 

End

 

Butt his ends with following error:

 

org.drools.rule.InvalidRulePackage: Rule Compilation error The method
yourFunction(List) is undefined for the type argTest

 

Can anyone please give me a hint why this going wrong?

 

Kind regards

Christian
