allows you add up to 409 fields on a page. When you reach this limit, typical system behavior includes being unable to select, move, or edit the page fields with an order number exceeding the 409-field limit. While this limit has no effect on the page at run-time, it has the potential to disrupt productivity during design time. If you find a page nearing the 409-field limit, you should use sub-pages to decrease the number of fields on a single page.
