Hi, 
I have created a simple process workflow and template files for it. (hello.ftl & helloTask.ftl) The first template has the below statement :
Enter some value <input type="text" width="200" name="abcvariable" /> 
and helloTask.ftl template prints the entered value like below :
Youentered : ${abcvariable}<br>

When I start the process I enter some data in that text box. Nex if I try to open the task list I get below exception :

"freemarker.core.InvalidReferenceException: Expression abcvariable is undefined on line 10, column 13 in HelloTask"

I dont want to add the parameters in the code file using hashmap. Since the control name becomes as process variable it should print the value isn' it?
I am trying to avoid eclipse here and do everything in webconsole.
