Hi.
I'm using the gwt-console and trying to set a parameter mapping to send some
variables from the process to a task.
First, the variables are setted in the process like:
<header>
<variables>
<variable name="myVariableA" >
<type
name="org.drools.process.core.datatype.impl.type.ObjectDataType"
className="String" />
</variable>
<variable name="myVariableB" >
<type
name="org.drools.process.core.datatype.impl.type.ObjectDataType"
className="String" />
</variable>
</variables>
</header>
The parameter mapping is:
<humanTask id="3" name="Revisar Solicitud" x="119"
y="143" width="162"
height="48" >
<work name="Human Task" >
...
</work>
<mapping type="in" from="myVariableA"
to="myVariableA" />
<mapping type="in" from="myVariableB"
to="myVariableB" />
</humanTask>
Then I have a ftl file for the task form like:
<html>
...
<body>
A value: ${myVariableA}</br>
Another value: ${myVariableB}</br>
...
</body>
</html>
With this code, when I select a task and click "View", I get the following
exception:

Is this a bug? or I'm doing something wrong?
Thanks in advance
