===========================

in this tag , i'm aiming to generate an fieldGen tag to be displayed on the ObsForm.jsp page.

As a start, I've hard coded values

    String widgetName = "org.openmrs.Patient";
    String formFieldName ="valueComplex";

in the tag, and am merely passing them into the appropriate place. ( see code)

my problem is, in order to make the tag display an auto complete box of patient instances, what do I pass in as the 'value' of the field Gen tag class ?

 should this be a list of all patient instances ? am rather stumped here....
