We have created a PDF dynamic form made up of several pages. Each page contains dynamic and non-dynamic subforms. Each dynamic subform displays a row of input fields by default, and every time a user clicks on a button, a new row is dynamically added to the subform (just like the Purchase Order sample form).
If all the dynamic subforms are kept in their default state (no new rows are added), the tab order works fine.
If any of the dynamic subforms are modified by dynamically adding new rows, then the tab order stops working. We have experienced two behaviors.
1) If no subsequent dynamic subform has been modified, once we tab to the last input field on the row added last, tabbing has no effect and the cursor remains on the last field.
2) if any of the subsequent dynamic subforms has been modified, once we tab to the last input field on the row added last, tabbing causes the cursor to set focus to the first field on the first dynamically added raw (not the default one) on the next first dynamic subform which was previously modified. Thus skipping over any other input field, part of a dynamic or non-dynamic subform(s), in between.
Is there a way to prevent a users from tabbing out of a dynamic subform? Or is there a way to enforce the tab order as to prevent the two behaviors we are experiencing.
Thanks
