Why is the number 2 displayed?

Question

Hi all,
I´m confused trying to work out why the code arg2 in
hash signs displays the number 2? I can´t see a 2 anywhere- Is
the fntest doing a len function? Thank-you very much

Answer 1

<CFFUNCTION NAME="fnTest" OUTPUT="YES">
<CFARGUMENT NAME="arg1">
<CFARGUMENT NAME="arg2">
#arg2#
</CFFUNCTION>
<cfoutput>#fnTest[1,2]#</cfoutput>
This code produces an error, as it should. Coldfusion
complains of an "Invalid CFML construct found on line 9 at column
20.". The offending line is the cfoutput line.
As Dan rightly hinted, you shouldn't call a function with
square brackets, but with normal brackets, so: fnTest(1,2) or
fnTest(arg1=3,arg2=5) or fnTest(arg2="myVar") ,..., and so on. The
last example, where just one variable is passed, is possible
because arguments are optional by default. However, we cannot do
fnTest() because the function explicitly requires arg2.
