;xxxxxxxxxxx REVISE FOR GRP-7426 use a Report Definition rule as a data source & Button control

A modal dialog is an interaction with the user — a form to be filled in or a statement to be acknowledged--that pops up in its own window on top of the application. The user cannot continue with other activities in the application before processing the form or dismissing the modal dialog.

You cannot use a modal dialog if the data source is a Report Definition.

How modal dialogs work

A modal dialog combines a pop-up window with a flow action as the front most screen where the user is working. The dialog box is centered in the viewing area. The flow action provides the section or sections containing the form fields the user is to complete. When the user submits the form, the system updates the work object and the modal dialog closes. The user can then continue working with the main screen display.

How to customize modal dialogs

Modal dialogs take their colors, corner shapes, and other settings from the application skin created by the Branding Wizard. The section governing modal dialogs is on the Custom Styling screen, in the Special category.
