Issue

The workflow designer does not show the SmartObject identifier property on a SmartObject event.

Symptoms

In rare cases after a SmartObject is created from a stored procedure, some of the identifier properties are not available on a SmartObject event in the workflow designer.

Resolution

One possible solution to this issue is to initiate the created variable with a null value in the stored procedure as the example below:

create procedure temp @Parameter1 varchar(50) = null

as

Select @Parameter1
