One embodiment is directed to a system or pop-up panel module for configuring a pop-up panel. The system or module include a controller and/or processor. The controller and/or processor may be configured to receive a plurality of actions requiring a validation, and invoke a call to a model layer to validate at least one of the plurality of actions. Based on a result of the validation, a message corresponding to the at least one of the plurality of actions is retrieved, and the retrieved message is stored in an object. The controller and/or processor may be further configured to provide a pop-up panel that references contents of the object and displays the message stored in the object, and to re-use the object to store a message for each of the plurality of actions requiring validation.
