Call to custom BO Action gives dump

Hi,

  My requirement is to display all inactive employees in the system.  Then the users selects an employee and clicks a button to convert him into a contact.

  I have created an OWL which queries the standard Employee BO and displays the list of inactive employees.  Everything works fine till now.

  Then I have added a button linked to an event handler, the event handler has the following functions:

1. Create a new instance of the custom BO -> works.

2. Call the custom BO action.  When this is added the OWL screen does not even load, it just dumps.

  Could you please let me know why this is happening?  And how do I call the custom BO action in order to create the contact?

Regards,

Sai
