Hi, The other day I've helped Sebastien with the task he explained at http://markmail.org/message/mmviy6tsv47g7rhr.
The problem we hit is that when an non-http thread needs to write to Native WebSockets connection it fails at Weld check for active context at ConversationPropagator#onRequestHandlerScheduled(). When Native WS creates the dummy RequestCycle at org.apache.wicket.protocol.ws.api.AbstractWebSocketProcessor.broadcastMessage(AbstractWebSocketProcessor.java:218) [wicket-native-websocket-core-7.0.0-SNAPSHOT.jar:7.0.0-SNAPSHOT] it also calls org.apache.wicket.request.cycle.RequestCycle.scheduleRequestHandlerAfterCurrent(RequestCycle.java:794) [wicket-core-7.0.0-SNAPSHOT.jar:7.0.0-SNAPSHOT] that notifies all IRequestCycleListeners about the scheduled request handler. https://github.com/apache/wicket/blob/master/wicket-cdi-1.1/src/main/java/org/apache/wicket/cdi/ConversationPropagator.java#L130 checks whether the conversation is transient and this leads to the error below. In the use case there is no usage of CDI in the non-http thread at all. It is just that ConversationPropagator as IRequestCycleListener is notified and it tries to do its checks. As a workaround I've try/catched ConversationPropagator.java#L130 and returned null in case of exception. Is there a better way to check for active context before trying to do: if (conversation.isTransient()) ?
