Play! framework: no data received <p>this is a route I defined:<br> <code>GET /user/:id controllers.Users.show(id: Long)</code></p> <p>this is the handler (in <code>Users</code> class) for this GET requset: </p> <pre><code>public static Result show(long id) { return ok("hello " + id); } </code></pre> <p>I get this error: </p> <blockquote> <p>No data received Unable to load the webpage because the server sent no data. Here are some suggestions: Reload this webpage later. Error 324 (net::ERR_EMPTY_RESPONSE): The server closed the connection without sending any data.</p> </blockquote> <p>this is weird because it's the only page with this problem and everything seems to be normal.<br> so why is it happening?</p>
