    <p>I know you've already solved the problem but I'll answer anyway so people know what's going on.</p> <p>1) removeAllListeners() only removes the array of callbacks for the event in question; it does not affect any other events at all.</p> <p>When you define an eventListener (i.e. on('xyz', function(){}) you append the callback function to an array indexed by the name of the event supplied. This array is a member of the object in question, in your case the "webSocket" object. webSocket.on("createRoom", function(){}) adds the function to an object similar to</p> <pre><code>webSocket.listeners = { "createRoom: [ function ], "someOtherEvent": [ function, function, function ] } </code></pre> <p>webSocket.removeAllListeners('createRoom') will simply remove the createRoom key and its associated value from the object without affecting any other events:</p> <pre><code>webSocket.listeners = { "someOtherEvent": [ function, function, function ] } </code></pre> <p>2) Though the roomJoin and messageReceived events were defined within the createRoom event's callback function, they are still operating on the same instance of the webSocket object. So you end up with a listeners object similar to:</p> <pre><code>webSocket.listeners = { "createRoom: [ function ], "main/roomJoin: [ function ], "chat/messageReceived": [ function ] } </code></pre> <p>Combined with the information from point #1 above, webSocket.removeAllListeners('createRoom') will yield the following:</p> <pre><code>webSocket.listeners = { "main/roomJoin: [ function ], "chat/messageReceived": [ function ] } </code></pre> <p>Just because these two events are defined within a callback for another event does not mean they are in anyway associated to that "parent" event. As you've figured out by now, the only way to remove these listeners is to remove them explicitly:</p> <pre><code>$('#exitButton').on('click', function() { // Removes websocket.removeAllListeners('createRoom'); websocket.removeAllListeners('main/roomJoin'); websocket.removeAllListeners('chat/messageReceived'); }); </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
