I tried this code in my application and it almost worked but not exactly.
When I selected more than one item, the parameter was saved in the database as: p1|p2 rather than p1,p2 as would be the normal case of html.
If I then go to the database and change it manually to p1,p2; then it displayed correctly in the administrator..
Any ideas for a fix?????????????????

I needed this
function fetchElement($name, $value, &$node, $control_name) {
(...)
// value string to array
$value = explode(',', $value);
return JHTML::_('select.genericlist', $options, $ctrl, $attribs, 'value', 'text', $value, $control_name . $name);
}
