Re: Validator::validate() reflection - null
Thanks David,
The error comes from the definitions in global tag of my validation.xml.
I could have copied them from one of samples which i tried.
Replaced them from the example in 20010702 and it works as expected

over it again. If a field is of type int, you don't
need to validate to see if it is an int. Also if you
have a field defined as an int, then you don't know if
someone entered something bad because you will always
get the default value of the field. So on the
ActionForm level it is good to preserve the user's
input so if it fails validation you can return the
value the user entered so it can be corrected. So an
ActionForm normally uses Strings except for
checkboxes, radio buttons, and select boxes where you
know the user can't enter anything bad. Then you can
have a bean with all the correct types (int, Date,
etc.), and convert the ActionForm's values to the
other bean. There are a couple of transformation
packages posted to help with doing this type of
conversion between objects. Here is the link.

I looked at your validator example again and began
to see that numeric fields
in form are defined in String.
I deduce the problem is in my design. My Meter bean
has meter1 of type 'int'
The getMeter1 returns 'int' and setMeter1 has 'int'
in signature.
It works without valdiation (as in
struts-exercise-taglib) so I didnt think it
could cause problem with Validator.
Am I right?
