Wicket Validation
Hey guys,
I have some business logic where when the set method is called, it first
validates the value. In finding a “bad” value, it then throws a custom
validation exception. We use this pattern all over the place.
Is there some way to handle this situation so that it’s a valid wicket
validation error?
Thanks for any tips.

Hey Sven, I considered this, but realized that models don’t have access to
the component, so I wasn’t sure how I would report the errors. Any tips
would be appreciated.

Hi,
you could use a custom model wrapper catching your exceptions and
reporting them as error messages.
Have fun

Hey Martin, well the exception is being thrown during the form submit
processing, but it just ends up as a big error on the page.

Hi,
Wicket cares about validation errors only during form submit processing.
In your case you could throw ConversionException during the 'convertInput'
phase.
I.e. in the beginning of the form submit processing Wicket will try to
convert the String input to the backend object (e.g. a String to Integer,
or to a Date, or to something custom).
If the setters are used at that time and the input is not valid then throw
ConversionException.
