I usually create a variable that is a folder value.  Then if i want 
different skin i just change the varible the different folder would have 
the different skins.  Something like: ($folderName = 'skin1';)
templates/skin1
templates/skin2
templates/skin3
etc...

$this->TemplateFile = 'templates/'.$folderName.'/templateFile.rwf.tpl';

Each skin folder has the same templates with the same names that map 
into the Controls, but the html/Smarty code is different.

Now for your code:
For starters I would take a look at  
http://www.rwfphp.org/rwfdoc/rwfPHP/Control.html#var$Controls
This inherited object contains some properties and methods we can use.  
I couldn't find the source of the problem right off the back, so I think 
if we make some changes we might see something different happen.  My 
changes are below:

The problem might be with the use of $controls in the MultiContainer, 
its not good (an easy to do with php) to override the Properties of the 
rwfphp classes.  Overriding methods is less problematic and some methods 
like GetTemplate are made to be overridden, but always be careful about 
doing it.

Here is the code in one piece:

<?php
require_once(RWF_DIR.'rwf/Web/UI/WebControls/WebControl.class.php');
class MultiContainer extends WebControl {
    var $controlsByNumber;
    var $select;
    function MultiContainer() {
        WebControl::WebControl();
        $this->controlsByNumber = array();
        $this->select = 0;
    }

    function addControl($control) {
       $this->AddControls($control->Name,&$control);
       $this->controlsByNumber[count($this->controlsByNumber)] = &$control;
    }

    function setVisible($n) {
       if(!is_numeric($n)) return $this->setVisibleByName($n);
       if($n >= 0 && $n <= count($this->controlsByNumber) - 1) {
          $this->select = $n;
       }
    }

    function setVisibleByName($name) {
        // $this->Controls is from the Control class
        if(isset($this->Controls[$name]))
            return $this->Controls[$name];
        else
            // Handle error here
    }

    function GetTemplate($smarty) {
        if(count($this->controlsByNumber) == 0) return "[Empty container]";
        return $this->controlsByNumber[$this->select]->GetTemplate($smarty);
    }

?>

ps - I would prefer that you would not swear while posting to the list.
