Last time I checked, CF _did_ have short circuit eval. Maybe you have a
slight typo in your code? This feature has been around since 4.01 I believe.
(Maybe earlier, someone feel free to correct me.)

Hi Ruslan,
Actually, CF 4.01 and above do support Short Circuit evaluation...
maybe you should upgrade.

Ruslan,
Every since CF4.01, CF has supported short-circuit logic. So the you're
first example *does* work in CF4.01+.

Hey Ruslan,
Sure... what you mentioned works for me all the time...
cfif IsDefined("somevar") AND somevar EQ "something"
Do this
cfelse
Do this
/cfif
However, the loop thing you mentioned

there is a better way like in c++, where it does lazy evaluation.
This is what I want:

/CFIF
I think this
Cold fusion uses Lazy evaluation.
I use the exact syntax you posted regularly in CF 4.5.1.

Some days you eat the bear;
CFIF (isDefined("somevar") AND somevar IS "something")
do something
cfelse
do nothing

I am not sure what version of CF you are running but you can do what you
want in 4.5.
The other way around it is to use CFPARAM to set it as empty then check it.
eg
cfparam name="somevar" default=""
cfif somevar is "something"
do something
/cfifi

Right you are. CF 4.0 does not have short-circuit evaluation but if you
really are running 4.0 you should probably upgrade to 4.0.1 regardless of
this problem. 4.0 thinks Febuary 29th never exists. And other glorious

I have had to write this kind of code over and
hmmm. I never noticed. Would have coded a few things differently. I'll check
it out tonight.

Last time
I must have been mistaken. I will try to go and see the exact code that was
causing that error.

The ability to "lazy" evaluation has been in ColdFusion since v 4.01
cfif IsDefined("somevar") and somevar IS "somestring"
