Groovy Script Task serialize error with HTTPBuilder

Hello, I am trying to write a script task in Groovy that implements a simple REST client to query a web service. The script works outside of the script task with the same environment that the engine is running in.—import groovyx.net.http.RESTClientfreedom = new RESTClient( 'http://api:api@localhost

THe REST-client is treated as a variable and is tried to be stored, while you don't want that. Userguide says:


<activiti:executionListener event="start" class="org.activiti.engine.impl.bpmn.listener.ScriptExecutionListener" >
  <activiti:field name="script">
    <activiti:string>
      def bar = "BAR";  // local variable
      foo = "FOO"; // pushes variable to execution context
      execution.setVariable("var1", "test"); // test access to execution instance
      bar // implicit return value
    </activiti:string>
  </activiti:field>
  <activiti:field name="language" stringValue="groovy" />
  <activiti:field name="resultVariable" stringValue="myVar" />
<activiti:executionListener>

So use "def" instead, when declaring the REST-client, so it's not treated as a process-variable.
