bene, questo e` il mio script all'interno del frame:

<script language="javascript">
pageFormMode = parent.groupForm.pageFormMode.value
groupName = top.groupForm.groupName.value
idGroup = top.groupForm.idGroup.value
top.location.href="groups.php?iconFilename='
<?php print($uploadedIconName); ?>'&FormMode=' +
pageFormMode + '&groupName=' + groupName +
'&iframeRefresh=1&idGroup=' + idGroup
</script>

bene, ...non mi rinfresca!!!
