Sorry you have to be a little more specific, for instance:
4. Select evaluation task --> Is this the Evaluation task that is read from the file
system (
https://github.com/droolsjbpm/jbpm/tree/master/jbpm-installer/sample/eval...
https://github.com/droolsjbpm/jbpm/tree/master/jbpm-installer/sample/eval...)
or is this a task that you created in Guvnor via Designer? If this is a custom process you
created with Designer, have you generated the task forms via designer too?
Not much we can do unless you show your bpmn2 and your generated task forms so we can try
to reproduce.

Hi,
Thanks for the reply. I am using the sample evalution provided in the (
https://github.com/droolsjbpm/jbpm/tree/master/jbpm-installer/sample/eval...
https://github.com/droolsjbpm/jbpm/tree/master/jbpm-installer/sample/eval...)
. I have attached task forms generated in guvnor and screenshots of execution in my local.
Also,i checked the screencast for jbpm console again and see that varibale
'content' is missing in InstanceData section in my local. This is autogenerated
one and I haven't done any changes in the bpmn file.

Seems like the issue is that content variable is not set. When you look at the exception:
*+freemarker.core.InvalidReferenceException: Expression reason is undefined on line+*
it refers to the reason expression that should be inside content variable and content
should be set as variable when self evaluation user task is created (with onEntry-script).
Could you take a look at server log if there are any exceptions when process enters self
evaluation user task?

Hi,
I tried to clean jboss(deleting repository,tmp) and restart the complete process. Now the
sample evaluation process itself is not showing up any more in jbpm console. And following
error is coming up in server logs whenever i click refresh in process view. I have to fix
this now to proceed any further.

The error most likely means that you did not build all packages in Guvnor before accessing
the the process view in the console. Also you say you have generated the forms with the
Designer, but the screen shots you attached are from
https://github.com/droolsjbpm/jbpm/tree/master/jbpm-gwt/jbpm-gwt-form/src...
https://github.com/droolsjbpm/jbpm/tree/master/jbpm-gwt/jbpm-gwt-form/src...,
so you must have uploaded them to Guvnor manually?
Would be nice if you could step-by-step describe your setup so someone can try to
reproduce.

Hi,
Forms are same as i am testing evaluation process given in installer. I have removed the
earlier installation now and started a fresh setup. Here are the steps followed.
1. Extract the full installer jbpm-5.2.0.Final-installer-full.
2. Run ant install.demo.noeclipse (I already have helios in my local)
3. Run ant start.h2
4. Start jboss standalone instance directly. I am not using ant start.jboss script to
start jboss.
5. Run ant start.human.task
6. Deploy Evaluation.bpmn(provided under
jbpm-installer\sample\evaluation\src\main\resources) to Guvnor repository.
7. open http://localhost:8080/drools-guvnor/ http://localhost:8080/drools-guvnor/. Check
the availability of evaluation process.
8. Use the option in process editor to generate human task forms. It generates two
forms(please check screenshot with assets).
Note: I get below error when click on the second view source link(highlighted in
screenshot)
XML Parsing Error: no element found
