    <p>I'm builiding a scheduling application using JSF 2.0 where users can add items to a calendar then edit those objects.</p> <p>I'm using AJAX quite extensively to keep the page from refreshing.</p> <p>The problem I am having is to get a return value from the function that is called using AJAX.</p> <pre><code>&lt;!-- ... form to fill --&gt; &lt;h:commandButton value="Insert"&gt; &lt;f:ajax execute="formField1 formField2..." listener="#{myBean.insert()}" onevent="processSave"/&gt; &lt;/h:commandButton&gt; </code></pre> <p>This successfully calls my JavaScript function <code>processSave()</code>.</p> <p><code>myBean.insert()</code> returns the <code>id</code> of the newly inserted row in the database</p> <pre><code>public String insert() { //... inserting data into database id = {id from database is obtained here} System.out.println("I have the ID here : " id); //this works return id; } </code></pre> <p>I've been trying to get this from the response object within JavaScript in the <code>processSave()</code> function.</p> <pre><code>processSave(data) { if(data.status == "begin") { // ation done here } else if(data.status == "complete") { // more actions done here } else if(data.status == "success") { //I am trying to get the ID here //I've tried looking into data.responseXML, but to no avail. } } </code></pre> <p>Is what I am trying possible using the current technologies?</p> <p>I think it would be possible to have a field in the page updated using the <code>render</code> component of the AJAX call, then use Javascript to go get the value. But I'm thinking this wouldn't be as clean?</p> <p>Thank you!</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.
