You also need to define what those events look like. I.e. what is the .name of the DOMError that they contain for the various error conditions that can occur here. The use-case is wanting to create a UI which displays error messages to the user on the form of "We were unable to set up a server to listen for incoming chat requests. Perhaps you already have another <chat protocol name here> server running in another application. If so, please try closing that application and press the 'connect' button again". For this to be possible the application needs to receive a machine-readable error which it can use to determine which error UI to display. / Jonas >> -----Original Message----- >> From: Nilsson, Claes1 >> Sent: den 13 maj 2013 12:58 >> To: 'Jonas Sicking'; public-sysapps@w3.org >> Cc: Edenbrandt, Anders; Isberg, Anders; Isaksson, Björn >> Subject: RE: Error handling for TCPServerSocket >> >> Hi Jonas, >> >> Yes, the error handling for TCPServerSocket might have to better >> defined. >> >> In the description of the steps for the TCPServerSocket constructor I >> guess that we should add a statement saying that an exception is thrown >> if the server socket cannot be created, for example because the >> implementation does not support TCP server sockets. >> >> However, I don't know if we need an event stating that the server has >> been successfully set up.
