jbpm - query all unassigned tasks -


i'm using jbpm 6.2 , i'm trying query tasks have not been assigned yet. taskservice doesn't seem (or @ least have not found proper method).

how can done?

i did using bamtasksummary table, not sure if way it.

to first tried bamtaskeventlistener @ runtimemanager (so started recording table):

defaultregisterableitemsfactory registerableitemsfactory = new defaultregisterableitemsfactory(); registerableitemsfactory.addtasklistener(bamtaskeventlistener.class); emf = persistence.createentitymanagerfactory("org.jbpm.persistence.jpa"); runtimeenvironmentbuilder builder = runtimeenvironmentbuilder.factory.get()         .newdefaultbuilder().entitymanagerfactory(emf).registerableitemsfactory(registerableitemsfactory)         .knowledgebase(kbase);

with code had problem, bamtaskeventlistener didnt have empty constructor in jbpm 6.2 , there problem in instantiation...i extended add empty constructor , worked fine:

public class bamtaskeventlistenerext extends bamtaskeventlistener{      public bamtaskeventlistenerext() {         super(null);         // todo auto-generated constructor stub     }      public bamtaskeventlistenerext(boolean flag) {         super(flag);         // todo auto-generated constructor stub     }      public bamtaskeventlistenerext(entitymanagerfactory emf) {         super(emf);         // todo auto-generated constructor stub     }  }

and registeded:

defaultregisterableitemsfactory registerableitemsfactory = new defaultregisterableitemsfactory(); registerableitemsfactory.addtasklistener(bamtaskeventlistenerext.class);

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
