Hi Ken,
Thanks. Issue has been filed:
https://jsftemplating.dev.java.net/issues/show_bug.cgi?id=5
I should have realized the space is the cause, i knew i used this
function many times before and don't have the problem. It was a puzzle
to me yesterday since i haven't updated the project and wondering why
the function doesn't work anymore.
thanks
Anissa.
