How would I go about deleting a contact in the GroupWise address book. I've tried the modifyItemRequest method but that just removes all the data but not the actual contact. So then I tried the removeItemRequest but get a 59911 error saying something about how the Container string is empty. What web method do I use and is this possible? Below is an example of my C# code using the removeItemRequest method.

private void DeleteGWContact(Contact aContact)
{
if (aContact != null)
{
aContact.container = new ContainerRef[1];
aContact.container[0] = new ContainerRef();
aContact.container[0].Value = GetSelectedAddressBookID();

removeItemRequest remReq = new removeItemRequest();
removeItemResponse remRes;
remReq.id = aContact.id;

remRes = _gwBind.removeItemRequest(remReq);
if (remRes.status.code != 0)
{
log(String.Format("Unable to delete contact \"{0}\": {1}",
aContact.fullName.displayName, modRes.status.description));
}
}
}
