Trapping bind errors to display as failed validation error

[sbmahs]

Hi,

I've successfully created validators to validate form input but I have one small issue: When a field that maps to a numeric field on command object is left blank or alfa data is entered, the following error is displayed:

Failed to convert property value of type [java.lang.String] to required type [java.lang.Integer] for property 'version'; nested exception is java.lang.NumberFormatException ...

Where do I trap this exception and

a) ignore it if the field is optional
b) display a more user friendly message.

Thanks very much. Regards,
Stefan

You need to add something like:

binder.registerCustomEditor(Integer.class, "myNumericProperty", new CustomNumberEditor(Integer.class, true));

The true is to allow empty entries.

NB. You'll still get validation error messages if you enter alpha characters - this is correct behaviour.

Thanks Katentim,

I've just checked the docs and both the built-in CustomNumberEditor and CustomDateEditor have a parameter to allow empty fields! Lovely
