Reference attributes in other view objects using groovy

This post is based on a question I asked to Mr.Andrejus Baranovskis's on his public Wiki. How to reference attributes in different view objects through groovy.

 And he answered me that its doable after exposing the ViewLink Accessor between the two view objects and then accessing the attribute through ViewlinkAccessor.AttributeName

He posted the last post for this year on his blog with an example, just follow the link:

Add Custom validator - nicely attached to InputText Field

After building your business components, and adding your view object through data controls to the jspx or jsff page as editiable field you need to do the following:

- Add a new Java bean to your application resources in my case I named it TestValidation.
- Select the InputText field, and in property inspector go to Behavior property, then inside Validator area select edit to add new custom validator.

- Then it will build a method inside your bean with list of params will be used during validation phase.

-  Write the business logic you need to check the value of the input filed, the object param contains the new entered value.
- Then throw the validationException with custom message to your current FacesContext.
- At runtime you will get a nicely error message attached to the InputText field.
