I'm trying to display a discrete list of records from a CDT (based on a user's previous selection) that include all read only fields and only one editable field but can't find a good example for an editable grid that does not include the ability to add/delete rows. It looks like I still need to create a main expression and a supporting rule but how do I do that without including the 'linkField' used to add/delete rows (which I don't need). I'm attaching the main expression rule (with the linkField rows commented out) and will add the supporting rule in a comment. My supporting rule doesn't display any errors but the MainExpression does ('Expression evaluation error at function a!applyComponents [line 100]
