    <p>I'm trying to extend the Groovy Mag Atmosphere Example (<a href="https://github.com/rbramley/GroovyMagJMS" rel="nofollow noreferrer">https://github.com/rbramley/GroovyMagJMS</a>) to broadcast to different clients. (Like in <a href="https://stackoverflow.com/questions/7199164/broadcasting-to-a-subset-of-subscribers-in-atmosphere">Broadcasting to a subset of subscribers in Atmosphere</a>)</p> <p>A client connects with url <a href="http://localhost:8080/GrailsTest/atmosphere/messages/?id=1" rel="nofollow noreferrer">http://localhost:8080/GrailsTest/atmosphere/messages/?id=1</a>. An id will be passed to the server. The new added lookupBroadcaster Method creates a new Broadcaster Object with the id. When I wanna broadcast a message, the client does not receive the result.</p> <p>Can somebody help me and maybe try it out?</p> <p>I'm added the atmosphere 0.8.2 library to BuildConfig.groovy to use mappings like '/atmosphere/messages/*'.</p> <pre><code>dependencies { runtime 'org.atmosphere:atmosphere-runtime:0.8.2' } class AtmosphereService { static transactional = false static atmosphere = [mapping: '/atmosphere/messages/*'] static exposes = ['jms'] @Subscriber(topic='msgevent') def onEvent(msg) { println 'onevent' def payload = msg if(msg instanceof Map) { // convert map messages to JSON payload = msg.encodeAsJSON() } Broadcaster b = lookupBroadcaster(msg["id"], false); b.broadcast(payload) return null } Broadcaster lookupBroadcaster(String id, Boolean createBroadcast) { return BroadcasterFactory.getDefault().lookup(id, createBroadcast) } def onRequest = { event -&gt; def req = event.request def id = req.getParameter("id") Broadcaster b = lookupBroadcaster(id, true); event.setBroadcaster(b); b.addAtmosphereResource(event) event.suspend() } def onStateChange = { event -&gt; if (event.message) { log.info "onStateChange, message: ${event.message}" if (event.isSuspended()) { event.resource.response.writer.with { write "&lt;script&gt;parent.callback('${event.message}');&lt;/script&gt;" flush() } event.resume() } } } </code></pre> <p>}</p>

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.
