I am getting an
exception from the params interceptor.
I have an action
with a setId(Long), and a hidden form field called id that initially has an
empty string value.
This used to work,
until the exception handeling was improved with the type converters. Now,
I get this error :
id - [Invalid
field value for field "id".]
which is because
of java.lang.NumberFormatException: For input string: ""
in
XWorkBasicConverter.super.convertValue(context, value, toType); at line
85.
I can see a couple
of soloutions
a) in my forms,
don't render the hidden input if there is no value for id (fair bit of
work)
b) create a custom
type converter for Long (and other numeric types) that convert empty string to
null (fairly easy)
c) modify the
XWorkBasicConverter to support the empty string to null conversion for Number
types. (every one can use this)
What are your
thoughts ?
