[rules-users] function in guided decision table

[Ioannis Christodoulou]

Nope, I still have a problem after building and deploying the project
(without validation, since that would fail).
When my application receives the new package, an exception is thrown saying:
unable to resolve method using strict-mode:
org.drools.core.spi.KnowledgeHelper.logRule

My action from the decision table is quite simple:
logRule("@{rule}", $level); //level is a class from my application
and in the row (the rule) I set it to <Test Rule>.

The drl contains (only) the function:
function void logRule(String rule, Level level) {
    System.out.println("Matched rule: "+rule+" for level:"+level);
}

I tried to call the function using FunctionName.functionName pattern, as
well as <package_name>.FunctionName.functionName pattern, without any
success.

Ευχαριστώ πολύ,
   Ιωάννης Χριστοδούλου
