Hi,

I have checked your code and it is working fine.I am not getting any error.

Workflow is started with Workflow Start Task and  it is directly send to Review Task.

Thanks,

Sanjay

I am using SDK 3.0.1 and All-In-One project. Does it make any issue?

[sanjaybandhniya]

I dont think it make any issue either you use sdk2/sdk3 all-in-one or separate repo and share.

Main thing here is proper way creation of bpmn file and register it,workflow model file and register it and make share configuration.
