The first one is a bug, that is fixed in RC3 when it comes out.
The second one is wrong, as the function needs to return a boolean for it to
make sense in an eval.

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)

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
