I believe that a parameter might be null when it's not defined.
Null is definitely != '', so the test "fails to fail"!
If you look at the JEXL syntax (the language you use inside ${...}):
http://jakarta.apache.org/commons/jexl/reference/syntax.html
There is a nice empty() function that tests if the expression is either:
- null
- an empty string
- an array of length zero
- a collection of size zero
- an empty map
So I think this should work:
<jx:if test="${not empty(cocoon.parameters.source)}">
