Thanks Tihomir for the reply.

My java code to start the process has the below.

| 
 | 
 | 
 | Map<String, Object> params = new HashMap<String, Object>(); |
| 
 | 
 | 
 | params.put("policyId", "testingpolicyId"); |
| 
 | 
 | 
 | 
 |
| 
 | 
 | 
 | ksession.startProcess("voluntaryProcess", params); |

I have added the variable "policyId" in the variable definition property of my process.

I am using guvnor 5.1 and the designer version is 1.0.0.55.

When I tried to access my variable in the ftl file as ${policyId},  I am getting the below error.
