Hi list, while trying to grasp the "tapestry way of doing things", I stumbled on this question:
I want to show a message in response to a submit. It is not a result of validation, but rather of the database state which is detected during data manipulation in the onSuccess event. For example, the submit is supposed to delete several entries in a database, some of which may have been removed by another process between the user selecting them and submitting the form. If this is the case, I want to show a friendly message to inform the user about this fact. Normally, after a submit, the same page should be re-displayed with updated data. I'm not sure how to incorporate the messages there. Can I use something similar to the <t:errors/> component for this? That one uses a wording adapted to the input validation and uses error colors which don't fit here. Maybe I need to implement some similar behaviour by hand via properties into which the messages are put and display these "by hand" in the tml template? Another way would be to use an "exception page". Can I use a special exception page that gets called automatically for some special type of exceptions? A normal page especially for user messages could be used, too, but what is preferred way? Is there a way that tapestry suggests for this situation, as it does for input validation?
