beandisplay hide label if value is null?
Is there an way with the beandisplay component to have it not show the labels
(and values) if the value is null or empty?
For example:
Label1 -- Value1
Label2 -- Null
Label3 -- Value3
Would display as:
Label1 -- Value1
Label3 -- Value3
If not then is there another way to dynamically do this without having to
check every single field for nulls?
<t:if test="object.value1">
// display it
</t:if>

You could use the exclude parameter
<t:beandisplay object="user" exclude="prop:excludes" />
public String getExcludes() {
// return a comma separated list of property names based on some logic or
null
}

Write a wrapper component around BeanDisplay and name it something like
BeanOptionalDisplay. That way, you only write the 'if (obj != null)' bit
one time.

And how to avoid NPE on beandisplay if the obj is null?
I dont want to test the null value every time that I need to verify the obj,
on my app there are data that is not required so I want to display something
like "Data no available" like grid does when there is no rows...
Suggestions?

Use the BeanModelSource to get a BeanModel, change it, then pass it to
BeanDisplay.
