This information is limited to adding hidden form data that is associated with a specific JCA table and that is identified by a specific table ('MYTABLEID') in the example code above). The hidden data may be defined as one or more hidden columns in the table, in which case a unique value may be submitted for every row in the table, or it may be associated with the table itself and not connected with any row or column, in which case one or more values may be submitted for the entire table. These two approaches may be combined within a single form submission or they may be used separately.

No provision is made for client-side generated hidden form data that is not associated with a JCA table, as this technique relies upon the 'submit' event that is signaled just before a JCA table that appears within a wizard (i.e., HTML <form/>) is submitted to the server.
