I'm trying to get validation to work in long running conversations:-
| @Begin(join=true)
| public String findVenues() {
| // Utility method, sets up an outjected DataModel
| findAll();
| // Redirect to result display page
| return "displayFoundVenues";
| }
|
| public String editVenue() {
| // Set the bijected venue to the DataModelSelection
| venue = selectedVenue;
| // Redirect to edit venue page
| return "editVenue";
| }
|
| @IfInvalid(outcome=Outcome.REDISPLAY)
| @End
| public String updateVenue() {
| // Clear the venues found in the previous search
| venues = null;
| // Redirect to the venue search page
| return "venueSearch";
| }
|
If any of the fields in the venue Entity are invalid an
| InvalidStateException: validation failed for:
uk.co.splendid.sms.model.venue.Venue
|
occurs.
If I 'split' the updateVenueMethod
| @IfInvalid(outcome=Outcome.REDISPLAY)
| @TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED)
| public String updateVenue() {
| return "confirm";
| }
|
| @End
| public String exit() {
| venues = null;
| return "venueSearch";
| }
|
and add in @TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED) then
it will work fine and displays the valididation error messages. However this
behaviour is not what I need - I want the user to be able to click the 'Save'
button and the changes to the object to be persisted if it is valid or the
screen redisplayed if it is not.
Any ideas? If I need to post more code/log messages I can do.
TIA
Peter
