Stefan Meyer commented on TRINIDAD-697:
---------------------------------------

This is a serious shortcoming. 
1. client side validation is not sufficient (see seam validation).
2. display of messages cannot be sufficiently done by using h:message or the 
built-in messages in the components. We need to be able to use facelets 
decoration to create messages. Thus we need full partial page rendering support 
upon validation failure. 

Ajax4Jsf has it - Trinidad should too.


> Trinidad has no way to re-render components to show server validation errors 
> or conversion errors on a partial update

> There is no built-in method in Trindad to have components re-render to show 
> validation errors and conversion errors during a PPR request with client-side 
> validation disabled.
> As a result, component messages are not shown to the user on validation and 
> conversion errors.
