seeking 'if' condition with form '($myVar in $myList)'...

I want to be able to find out if $myVar is in $mylist.
Is there syntax to handle this w/ WM template
scripting?
## Here is my list
#set $myList = [ "one", "two", "three" ]
## Here is the variable I'm looking for
#set $myVar = "two"
## I want to do this
#if ( $myVar in $myList ) {
do something...
}
#else {
do something else...
}
In my particular case, $myList is a java.util.Vector
made up of composite objects - each object has a name,
value, etc. To keep maintenance simple, I wanted to
avoid doing a multiple-condition 'if' statement like
this:
#if ( ($myVar==$possibility1) ||
($myVar==$possibility2) ||
($myVar==$possibility3)
etc. ) ) {
do something...
}
#else...
To give a fuller picture, my close-to-ideal
pseudo-code looks like this:
#set $myList = [ "one", "two", "three" ]
#foreach $compositeObj in $someRuntimeList {
#if ($compositeObj.name in $myList) {
do something
}
#else {
do something else...
}
}
I've tried to turn around the 'if' condition using
this syntax:
#if ($myList.contains($compositeObj.name)) {
but I get a 'NoSuchMethodException on a
Ljava.lang.Object'.
Thanks for any pointers.
I'm willing to do some coding if we wanted to add this
to the codebase - only, not sure if I could even
understand enough of the engine (Expression.java
maybe?) to know where to start hacking.
