This is an interesting approach, but way more overhead that I was hoping

PropertyConduit or something.  So, I could do
model.add(new_prop).addValidator(required);

I guess I'll file a JIRA for that.
  

Hello Kevin,

Did you move on on this issue ? I think your idea is really the best way 
to go, and it seems rather simple to add to PropertyEditor.

Or perhaps did you find a better solution ?

Re: [T5] BeanEditForm validations

[Hugo Palma]

You can do your validations in the onSuccess method in your page class 
like what is described here 
http://tapestry.apache.org/tapestry5/tapestry-core/guide/validation.html


All you do is access the edited object instance and use the BeanEditForm 
object to register the errors.


Hope this helps...

Hi,

Is there anyway to configure validation for a BeanEditForm other than with
the Validate annotation?  I'd like to have validation, but really can't
apply the annotations because I'm working with classes coming out of a
library.

I was hoping to be able to do this via the BeanModel, but I can't find a
way.  Any help would be much appreciated.

Thanks,
Kevin

I see at least two other way, one simple and one other a little more 
complicate.


The first one is to use the validate parameter in a property editor 
override in the BeanEditForm template.
See Property Editor Overrides in 
http://tapestry.apache.org/tapestry5/tapestry-core/guide/beaneditform.html
You might also add your custom property editors with their  template 
(and  so their  fields with validate  parameter).


The other one is the programmatic way, but you should not need it for 
common use of BeanEditForm.
If you want to customize globaly the validation proces,  you may extend 
the PropertyEditor component and play with FieldValidator and  
fieldValidatorSource service. You also will have to extend the 
BeanEditor component template to use you new property editor, and the 
beanEditForm so that it uses the new BeanEditor.
If you want, I have an example of such a thing here : 
http://svn.forge.objectweb.org/cgi-bin/viewcvs.cgi/interldap/interldap-wui-common/trunk/src/main/java/org/interldap/wui/t5lib/components/ldapentry/

A brief description :
* MyPropertyEditor is just a copypast of T5 PropretyEditor, with some 
visibility change on methods, you may forget it ;
* ** AttributeEditor ** is a special editor for the kind of attribute I 
have to deal with in my app. It extends MyPropertyEditor (read 
PropertyEditor) and
  It is the intersting component in which my personal validation 
process is done. Basically, I want to add a required validator if the 
attribute has a mandatory parameter set to true.
* AttributeBeanEditor  EntryBeanEditor. I think they are not to 
interesting for what you want to do, but if you look to their template, 
you will see that AttributeBeanEditor calls  AttributeEditor and that 
EntryBeanEditor calls AttributeBeanEditor.


Hope it will help !
