             Summary: Calling static Java method from DMN model (Drools Business Central)
                 Key: DROOLS-5577
                 URL: https://issues.redhat.com/browse/DROOLS-5577
             Project: Drools
          Issue Type: Bug
          Components: DMN Editor, dmn engine
    Affects Versions: 7.40.0.Final
            Reporter: Kristina Mandekic
            Assignee: Guilherme Gomes
         Attachments: Artifacts.PNG, Artifacts0.PNG, DroolsNewTypes5-0.0.1-SNAPSHOT.jar, dependencies.PNG, stdev 0.PNG, stdev 1.PNG

When calling static Java method {{stdev_a}} (which I created in a new Java Maven project) from Drools Business Central DMN project/model, I'm getting following error:

 
{code:java}
DMN: Error compiling Java function 'stdev' on node 'stdev': Error resolving external function as defined by: function(val) external { java: { class: ""com.samplea.drools.DroolsNewTypes5.StandardDeviationA"", method signature: ""stdev_a(java.lang.Number)"" }} (DMN id: _3B4B6CBE-847B-4488-8754-214F506BBB48, Error compiling the referenced FEEL expression){code}
 

Also, how to view logs of DMN model when it has build errors?
