[WebMacro-user] seeking 'if' condition with form '($myVar in $myList)'...

[Peter S. <sh...@ya...>]

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.
