[ic] It seems that [if]tag return nothing when result is 0.

[interchange-users@interchange.redhat.com (murahashi)]

I have strange behavior of [if] tag below.
I want to have 0 or 1 from the following sample.
In case of A or B , It works.
It seems that [if]tag return nothing when result is 0.
Is that right? Am I something wrong?
