Hi,
Messages of the type: ERROR, WARNING, or STANDARD are stored as constants in the interface IMessage<Name der Component>.java which is generated by the generation framework on component level.
ERROR MESSAGE IN TABLES:
Errors can appear in table views for different reasons. For example, a user may enter invalid data, or certain items from a set cannot be posted. These cases have to be handled differently.
INPUT ERROR
If a user enters invalid data, highlight the erroneous fields and scroll the table to the first field where an error occurred.
If an error message is needed, place it below the table view or - if possible - in a table row directly below the row where the error(s) occurred.
Table views will have a status bar, where the error message will appear. Place the cursor into the error field and scroll the table to make the field visible in case it is hidden from view.
If there is more than one error field, display the message for the first error field, place the cursor into that field and scroll the table to make it visible if necessary.
If the cursor is placed into a subsequent error field, display the message for the respective field. If an error is corrected move the cursor to the subsequent error field if there is one and display the respective error message.
If the focus is outside the table view, display the first error message again.
WARNING MESSAGES:
If the user of the example application chooses Rent without first specifying a vehicle type, an appropriate warning message must appear. If the user has selected a vehicle type, ResultView displays the vehicle type.
In the following procedure, you implement a warning message in the message pool and the onActionRent() method. You can display the warning message on the user interface using the IWDMessageManagerinterface. You can access this interface in the controller code using the shortcut variable wdComponentAPI.
Regards,
Arun
