InvitationListener does not seem to working. #36

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
InvitationListeners are dispatched in MultiUserChat.InvitationsMonitor.init().

in processPacket(), 
MUCUser mucUser = (MUCUser) packet.getExtension("x", 
"http://jabber.org/protocol/muc#user") 
throw a ClassCastException.
Because packet.getExtension() returns a instance of DefaultPacketExtension.

This logic needs a instance of MUCUser.
and a instance of MUCUser is made by MUCUserProvider.
But, MUCUserProvider was not used in asmack. (I used grep command)

Why? I don't understand. Is this InvitationListener not running still once?

I can run it!

XMPPConnection mConnection = new XMPPConnection(config);
mConnection.connect();
mConnection.login(login, password, resource);
ProviderManager pm = ProviderManager.getInstance();
pm.addExtensionProvider("x", "http://jabber.org/protocol/muc#user", new 
MUCUserProvider());
MultiUserChat.addInvitationListener(mConnection, mInvitationListener);

Exactly, aSmack doesn't add package extensions per default. This is bad when 
you get started (as you need to lern how to register those) but it's good for 
production (no I don't want this hashtable monster extension!).

Good luck and happy coding :-)

PS: You should register your extensions ONCE BEFORE login / connect :-)
