Displaying the the label of a select element by binding a BO value (id)

Content

Summary:

    I have a business object called "request".  I have a "New Request" with a select element called "Job Title".  It is populated with an SDP that gets data from a BO called "JobTitles" that contains application data (non transactional data).  The JobTitle BO has a label and id column, and that is what I map to the label / value of the select element.  The value of the select element is bound to the $page.variables.request.jobId variable (which is obviously a variable based off the request BO).  Upon clicking submit we store the new request with the selected jobId.
