if NOT help
I have a template that I am trying to get to work && it's 1:30 am.
I have a variable that will equal a character (i.e. "a")
If the variable is NOT zero length string (i.e. ""), I want to output
something.
Even though I output the variable's value and display it, I can not get the
if !(
#set($a = $b)
a is $a
## I always is "a is test" when the template is run from the above line
## this is an if statement with a NOT operator
#if (!$a == "")
I never see this, although a is not an empty string
#else
I always see this, BUT i don't want to. a is not an empty string
#end
I am seeing the same behavior in 1.2 and 1.3 velocity
Thanks!
