constraint-handlers dont work

[ltardioli]

Hello ppl,

I trying to do a validation using a constraint-handler in my share-config-custom.xml file. I have a model and a form that is working fine, but the validation just doesnt works;

The snippets of my code:

<property name="axcl:clienteContato">
               <title>Nome contato</title>
               <type>d:text</type>
</property>
‍‍‍‍‍‍

<field id="axcl:clienteContato" label-id="prop.axcl_clienteContato">
                  <constraint-handlers>
                     <constraint type="MANDATORY" validation-handler="Alfresco.forms.validation.mandatory" event="keyup" />
                  </constraint-handlers>
</field>
‍‍‍‍‍‍‍

I turn on the debbug mode and seems that the constraint dont exist.
I've looked for something in logs files but there isnt a thing about that.

Anyone knows what I missing?

Thanks!

Ah, I'm using Alfresco CE 4.0e

Hello,

why are you trying to do a mandatory validation with an explicit validation handler? Why not simply make the property mandatory or set the mandatory attribute on the field configuration?
In order for a constraint validation handler to be invoked, the relevant constraint actually has to be present on a property / field definition. Unless you mark the property or the field definition as mandatory, the "MANDATORY" constraint won't be present and your mapping won't be evaluated.

Hello AFaust,
this is just a simple exemple to test the handlers. Actually I want to do another kind of validations on my fields.
For exemple, do a post to a webscript to get some values and fill the fields with it.

If I do sometihng like:

<dependencies>
            <js src="/share/res/js/formCustomFunctions.js" />
</dependencies>

<field id="axcl:clienteContato" label-id="prop.axcl_clienteContato">
                  <constraint-handlers>
                     <constraint type="MANDATORY" validation-handler="Alfresco.forms.validation.myCustomFuncion" event="keyup" />
                  </constraint-handlers>
</field>
‍‍‍‍‍‍‍‍‍‍‍

and put my formCustomFunctions.js in webapps/share/js and in my model definition set the property as a mandatory attribute, it is supposed to work?

Thanks!

Hello,

no. First of all, constraint-handlers is to be defined globally, not on a per-field basis, and second of all, you should not override MANDATORY, since all mandatory fields will then be validated with your custom handler.

Are you saying that is impossible define constraint-handlers per-fields or it is possible but is not a good pratice?

Hi,
We are also facing the same problem while creating custom constraint handlers for a particular field. Now if we need to define the constraints globally, in which file we should define that. Please reply soon.

Thanks

I think there are something in the wiki that explain how to add you own constraint and then call it with event-handler check this http://wiki.alfresco.com/wiki/Content_Model_Constraints in the section Writing Further Constraints
