in the line:
e.getRoomID().setAttributeOnServer("selectedButton", this, true)
first, the attribute 'value' has to be a string. so i'm guessing you
want something like this:
setAttributeOnServer("selectedButton", "button3", true)
second, e.getRoomID() only gives you the string ID of the room.
setAttributeOnServer() is a method of URoom, not String. if you are
using the basic structure of uSimpleChat, then you can get a reference
to the room via ChatRoomView's instance property 'room'. as in:
room.setAttributeOnServer("selectedButton", "button3", true)
if not, you have to use RoomManager.getRoom(). you can obtain a
reference to RoomManager using UClient.getRoomManager(). for example,
within your UClient subclass, you would do this:
getRoomManager().getRoom(yourRoomID).setAttributeOnServer("selectedButton",
"button3", true)
