Problem to customize views in UWL

Hi,

I am trying to create custom views in UWL defining custom attributes for a Task ID. I have followed the approach on these links:

However, when I receive the task, the associated custom view is not displayed in the UWL. I have checked the new configuration XML file that I have created, but I haven't seen possible mistakes.

Why is not the custom view displayed? Have I to modify some configuration XML file?

Thanks in advance,

Samantha.
