Anne Jessel commented on OFBIZ-4393:
------------------------------------
value="null" definitely doesn't work. It's what I tried first before looking at
the code. Is that what should work? The current code compares value variable
with null, but I can't see how value can ever be null, as it has the value
returned by org.w3c.dom.Element.getAttribute, which doesn't return null. I
can change patch so it looks for String "null" instead of using isEmpty.

> condition-expr tag in view-entity can't be used to compare a field with null.
> An absent value attribute is read as an empty string, and the code currently
> checks for value being null to know when to compare against null.
