Hi,
As I wrote in my previous post "Native WebSockets - cookies and last
handler question": In WebSocketResponse many methods throws
UnsupportedOperationException. Some of them can be customized now
thanks to WICKET-6054.
But I have found another problem with WebSocketResponse.sendRedirect()
method. When you send a message using
IWebSocketConnection.sendMessage() and an exeption is raised somewhere
during processing of this message you can get the following exception
(the orignal exception is lost):
Error during processing error message
java.lang.UnsupportedOperationException

This is because WebPageRenderer by default calls redirectTo method. So
it looks like WebSocketResponse.sendRedirect() should not throw
exception in the default implementation?
