[rules-users] Unable to map process variables into WorkItem.

[Kris Verlaenen]

Have you also defined the "fact" process variable? You can do this by
clicking on the background of you process in the editor and updating the
variables parameter, or in the header in xml:

<header>
  <variables>
    <variable name="fact" >
      <type name="org.drools.process.core.datatype.impl.type.ObjectDataType"
            className="org.drools.ProvFact" />
    </variable>
  </variables>
</header>

Otherwise the process won't know where to find the "fact" variable
(because you could have multiple, nested variable scopes if you start
using composite nodes).
