>             Project: Wicket
>          Issue Type: Bug
>          Components: wicket-native-websocket

> After upgrade to 7.5.0 the following exception is thrown when the WebSocketBehavior is rendered:
> {code}
> ...
> Caused by: java.lang.IllegalArgumentException: Argument 'baseUrl' may not be null or empty.
> 	at org.apache.wicket.util.lang.Args.notEmpty(Args.java:64) ~[wicket-util-7.5.0.jar:7.5.0]
> 	at org.apache.wicket.protocol.ws.api.BaseWebSocketBehavior.renderHead(BaseWebSocketBehavior.java:100) ~[wicket-native-websocket-core-7.5.0.jar:7.5.0]
> 	at org.apache.wicket.protocol.ws.api.WebSocketBehavior.renderHead(WebSocketBehavior.java:62) ~[wicket-native-websocket-core-7.5.0.jar:7.5.0]
> ...
> {code}
> It seems to me that an empty String should be accepted here. I have checked and it worked fine in 7.4.0 with an empty String in {{baseUrl}}. The same for {{filterPrefix}}. An empty String is actually set in certain cases in {{WebSocketSetting#getFilterPrefix()}}.
