> I put an object having a method that returns an array of Integers in the context
> with contents
> [100,100,NULL,NULL,...]
> Then looping over the contents using
> #foreach ($elt in $Object.List) $!elt #end
> ALL entries become 100 with output: 
> 100 100 100 100 (...)
> instead of the expected
> 100 100 
> When converting all null objects to say new Integer(0) in the 
> getList() body before returning the list, output becomes
> 100 100 0 0 0 0 0 
> Apparently null values are not treated as first citizens,
> Cheers,
