Subject RE : [Validator] Multiple Form's Fields for the same property - Form inheritance
Date Fri, 17 Feb 2006 14:35:51 GMT
Actually, for Form inheritance, we are using the field's property: If at
least one field for a particular property exists in a form (sub-form)
then we ignore all fields for the same property defined in the parent
Form (super-form).

Having user-defined field's keys we should be able to manage the Form
inheritance validation overriding at the field key level!

Why if, beside of generating real unique Field's key in the scope of the
Form we let the user explicitly indicate the field's key (not just the
property) in a validation rules xml?. For that, we need to add "key" as
an optional attribute for field in the dtd. 

Or, do not generate field's keys at all? ... having the user to assign
unique keys in case of conflicts (more than one field for the same
property). The point is that to be backward compatible we can't enforce
field's key uniqueness because I feel that using different fields for
the same property is not a rare practice.

Objet : [Validator] Multiple Form's Fields for the same property

In order to override default validator messages, the msg's name refers
the validator name. 
 
How can I distinguish two validations with different messages using the
same kind of field's dependency?
 
Adding different Fields into the same Form for a same property is a kind
of solution (another one is to create identical mask1, mask2, mask3, .
but no no!):
 
<form name="AForm">
            <field property="a" depends="mask">
                        <msg name="mask" key="error.a.mask" />
 
<var><var-name>mask</var-name><var-value>${MASK}</var-value></var>
            </field>
 
            <field property="a" depends="validwhen">
                        <msg name="validwhen" key="errors.a.1"/>
 
<var><var-name>test</var-name><var-value>TEST_1</var-value></var>
            </field>
 
            <field property="a" depends="validwhen">
                        <msg name="validwhen" key="errors.a.2"/>
 
<var><var-name>test</var-name><var-value>TEST_2</var-value></var>
            </field>
</form>
 
There is a field list in Form with all those fields (the three of then
for the same property). This list is used to validate and everything
seem to be fine  ..  
 
However, the Field's unique key is presently associated to the Field's
property. 
 
While dealing with Form dependencies (using Form's extends) the Field's
key is being used as a key in a Map of fields (coherent with the
uniqueness of Field's key) . Obviously, it makes illegal the use of
"Multiple Form's Fields for the same property".
 
What we did then was:
 
We added support into Form for Multiple Fields for the same property,
using a suffix to field's key if more than one field are used for the
same property. 
 
What do you think?
