Hi guys,
Do you guys support the notion of validators like XWork validators?
Since WebFlow uses Spring validators could be configured
declaratively. If you're interested I would be happy to create a BNF
file for something like this:
{ firstname : length of form.firstname > 0 : "First name must not be empty" }
{ firstname : length of form.firstname <= 30 : "First name must be no
longer than 30 characters" }
{ age : form.age is number : "[${form.age}] is not a valid number" }
{ age : form.age > 18 : "You must be 18 years or older" }
{ age : form.age <= 110 : "We do not do business with the undead" }
Kind regards
Steven Devijver

At the moment SWF does not have any direct binding & validation support of
its own: it just uses the Spring binding and validation infrastructure
(DataBinder, Errors, Validator). I don't think binding and validation is
really a feature that we should build *into* SWF. Instead we need to
integrate with existing solutions.
Could you elaborate on the "XWork validators" a bit?

I hear you. It's just that I really would like to see declarative
validation rules. Besides, a validator that would support this would
simply be a specialization of the Validator interface.

This example says it all:
<validators>
<field name="bar">
<field-validator type="required">
<message>You must enter a value for bar.</message>
</field-validator>
<field-validator type="int">
<param name="min">6</param>
<param name="max">10</param>
<message>bar must be between ${min} and ${max}, current
value is ${bar}.</message>
</field-validator>
</field>
<field name="date">
<field-validator type="date">
<param name="min">12/22/2002</param>
<param name="max">12/25/2002</param>
<message>The date must be between 12-22-2002 and
12-25-2002.</message>
</field-validator>
</field>
<field name="foo">
<field-validator type="int">
<param name="min">0</param>
<param name="max">100</param>
<message key="foo.range">Could not find foo.range!</message>
</field-validator>
</field>
<validator type="expression">
<param name="expression">foo > bar</param>
<message>Foo must be greater than Bar. Foo = ${foo}, Bar =
${bar}.</message>
</validator>
</validators>

This doesn't seem to be specific to SWF: as you say, in theory it's just a
special, configurable Validator implementation (we actually made a
commons-attributes driven validator on my current project). What is the
status of "declarative input validation with Spring" in general? Is there
anything in the sandbox? Integration with commons-validator or XWork
validators?

Good point, I'll have a look at that.
