[enhancement request] option to hide null feilds in <f:display bean="user" />

is great. However if its a big domain object (such as user with perhaps 20 nullable fields), it would be fantastic to have an option to not display all the null ones.

This one addition would save us hundreds of additional lines of code doing each field by hand.

Start by locating the implementation of the tag and how it renders bean properties. Add the requested hideNull option, then verify that fields with null values are omitted while non-null fields remain displayed.
