-Adam,
first, thanks for all those explications. but I've still a problem with
my
validator using 'validwhen'.
I've seen first, that I don't have any "errors.validwhen = mymessage"
line
in my messageResource file ?
I guess I need to add it and I did it.
Otherwise, I've now clearly understood (I think so...) how It work.. but
have a look .. I've tried that :
<field property="enterpriseName" depends="validwhen">
<arg0 key="error.inscription.entreprise.nom" />
<var>
<var-name>test</var-name>
<var-value>((*this* == "hello"))</var-value>
</var>
</field>
I think it sould warn me each time my field is not "hello".. but it does
not.
I think now it's time to explain you clearly what I'm trying to do.
I've got a select tag wich determine if some fieds appear or not.
"if select value > 1, some input:text tags appears, and there aren't
present
is select value=1."
Maybe should I "hide" fields rather than "not display" fields.. ??
thx

Ok, sanity-check time. Make sure your field names are all spelled
correctly. Also, are any errors being output to the form? I had
errors
displaying and it turned out that the validator was doing exactly what
I
was asking it to do and the problem was that I just didn't understand
the "validwhen" validation rule.
I've found that overriding toString() on my form bean and having it
dump
the contents of all the fields is an excellent way to see with what
values the bean is being populated. You can then call
System.out.println(this) (or use a logger) in your bean's
validate(...)
method to see what values your bean has. Make sure the
subscriptionType
is set to the value you expect.
Also, your rule basically reads now as "the field enterpriseName is
valid when the subscription type is greater than or equal to 1." So,
e.g., if your subscription type is a drop down list that only contains
the values 1,2,3,4, the enterpriseName field will always be valid.
Give that a whirl and let us know.
cheers,
-Adam
