You can just use JAVA:
<excludeif property="ac:faxPhoneExtension" match=null>
Ext. <DISPLAY property="ac:faxPhoneExtension">
</excludeif>
<% if (ac.getFaxPhoneExtension() == null) { %>
Ext. <DISPLAY property="ac:faxPhoneExtension">
<% } %>
It's as easy as that...

Subject: Re: MATCH=null bug in JRun?
I've seen the same thing. I'm using an ugly work-around where I actually do
the test on the string "null". Of course, this only works on String objects
and I have to initialize to the string "null" in my beans instead of using
the "null" keyword.
A bigger problem to us has been that JRun does not support nested
<INCLUDEIF> or <EXCLUDEIF> tags. The result is always a nasty
NullPointerException. Have you run into that?
