Description
Unortunately the value and index is not accessible for displaying together with
the message. For example I would imagine:
<field property="email" depends="email" indexedListProperty="mylist">
<arg0 key="${this:value}" resource="false"/>
<arg1 key="${this:index}" resource="false"/>
</field>
So in the message would appear the value of the field email and the index of the
element in collection.
And more: for ValidWhen would be nice to have the value of the other field as
well ("${fielddane:value}").
I've put 'enhancement' but IMO it is the BASIC and trivial functionality which
validator should implement.
I said 'trivial' - it seemed to me. But after looking into the code of Struts
and commons-validator I don't think any longer that it is trivial. Simply
because not clean design of validator - example: commons-validator is treating
the indexedListProperty (reading from the bean indexedProperty), but reading the
value of the field is done in Struts (public static boolean validateMask(...)).
So there is no clean way now to read value of the bean on common-validators
level. And there is no clean way to read position/index in indexedProperty on
Struts level. It is what I mean not clean design.
I think validator needs real and smart refactoring before implementing this
feature (together with nested indexedListProperty).
(I recently moved from in-house C++ framework to JAVA-WEB-STRUTS and I found
plenty of strange limitations of STRUTS modules, I hope that I will spare time
at work to implement and give some patches)
