FAILURE: Exception occured while performing the operation. --> Changing from template from default to a custom form template

Hi guys,

I ran into the following issue:

When changing the request template of an existing default request to one of our custom templates, I receive the following error:

"FAILURE: Exception occured while performing the operation."

When searching through the log I can see the following issue:

[13:06:11:798]|[01-30-2017]|[com.adventnet.servicedesk.workorder.action.WorkOrderAction]|[SEVERE]|[70]|: update of workorder 39903failed. Exception while updating Workorder. Unknown column GUDF_CHAR9 in the table WorkOrder_Fields|

[13:06:11:798]|[01-30-2017]|[com.adventnet.servicedesk.utils.HdServiceDeskUtil]|[SEVERE]|[70]|: FAILURE :Exception occurred while performing the operation.|

I've checked the database and see that there is no such column in the WorkOrder_Fields table.

Any idea why I'm getting this error and how I can resolve it?

Thanks!
