    <p>After toying around with this for hours, I simply cannot find a solution. I'm working on a WebSocket server using "node.js" for a canvas based online game I'm developing. My game can connect to the server just fine, it accepts the handshake and can even send messages to the server. However, when the server responds to the client, the client doesn't get the message. No errors, nothing, it just sits there peacefully. I've ripped apart my code, trying everything I could think of to fix this, but alas, nothing.</p> <p>Here's a stripped copy of my server code. As I said before, the handshake works fine, the server receives data fine, but sending data back to the client does not.</p> <pre><code>var sys = require('sys'), net = require('net'); var server = net.createServer(function (stream) { stream.setEncoding('utf8'); var shaken = 0; stream.addListener('connect', function () { sys.puts("New connection from: "+stream.remoteAddress); }); stream.addListener('data', function (data) { if (!shaken) { sys.puts("Handshaking..."); //Send handshake: stream.write( "HTTP/1.1 101 Web Socket Protocol Handshake\r\n"+ "Upgrade: WebSocket\r\n"+ "Connection: Upgrade\r\n"+ "WebSocket-Origin: http://192.168.1.113\r\n"+ "WebSocket-Location: ws://192.168.1.71:7070/\r\n\r\n"); shaken=1; sys.puts("Handshaking complete."); } else { //Message received, respond with 'testMessage' var d = "testMessage"; var m = '\u0000' + d + '\uffff'; sys.puts("Sending '"+m+"' to client"); var result = stream.write(m, "utf8"); /* Result is equal to true, meaning that it pushed the data out. Why isn't the client seeing it?!? */ } }); stream.addListener('end', function () { sys.puts("Connection closed!"); stream.end(); }); }); server.listen(7070); sys.puts("Server Started!"); </code></pre> <p>Here's my client side code. It uses Chrome native WebSockets.</p> <pre><code>socket = new WebSocket("ws://192.168.1.71:7070"); socket.onopen = function(evt) { socket.send("blah"); alert("Connected!"); }; socket.onmessage = function(evt) { alert(evt.data); }; </code></pre>

    1. COWhat's the client side? Chrome native-WebSocket builds? Flash socket fallback?

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.
