Exception in Approval Process

Hi,

I am working on creating an approval process. To block an account I need it to go through some approval first.

I have followed all the steps as mentioned in the help doc but I am facing some issues.

I have created a custom BO (CustomerBlock.bo) and an EC. I have embedded the EC in Account TI. This contains some fields which need to be filled and then submitted for approval. I have provided a button which invokes submitForApproval action on click.

For the custom BO i have created the approval process, approval and notification tasklist views are added to Account workcenter view.

In submitForApproval action, I am assigning EmployeeIDs to requester and RM approver.

SubmitForApproval action is executed successfully, but on saving the Account I am getting an exception. The exception is not thrown if I remove the tasklist views from the account workcenter view.

Any Idea what could be the issue here? Please help.

Regards,

Ambuja
