; if you are unsure about what indeterminate state a list object should be in, pass FALSE. Most GenItemGroups do not need to worry about their indeterminate state.</P>
<P>
None of the messages which alter the state or number of selections cause an apply or status message to be sent out by the GenItemGroup. If you wish to send out an apply or a status message in these cases, mark the GenItemGroup modified and send the object <CODE>
MSG_GEN_APPLY</CODE>
 or <CODE>
MSG_GEN_ITEM_GROUP_SEND_STATUS_MSG</CODE>
