Working with Named Bind Variables

When you use the built-in ExecuteWithParams operation (this operation is available if there are bind variables in the VO):

You can drop the operation from the Data Control Palette to create an ADF Search Form to allow users to search the VO on the named bind variable values.

Your search fields corresponding to the named bind variables inherit bind variable UI control hints for their label text. You can define them as part of the View Object component.

You can drop the custom operation from the Data Control Palette to create an ADF Search Form to allow users to search the View Object on the parameter values.

Your search fields corresponding to the method arguments do not inherit label text UI defined in the control hints. Instead, you need to define UI control hints for their label text by using the Properties selection from the shortcut menu of the page definition variable corresponding to the method argument.
