    <p>guys i'm new and i'm not english. I have a problem with using js setInterval that simulate a user click, every X seconds, on submit button. In the page there is only one h:form and h:commandButton. I use a profiler and i see that the java.util.HashMap increase continuosly it's size. After some hours the used heap size is growed a lot respect the start point.</p> <p>Please help me, this problem make me crazy.</p> <p>This is the code:</p> <pre><code>&lt;?xml version = "1.0" encoding="utf-8"?&gt; &lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"&gt; &lt;html xmlns="http://www.w3.org/1999/xhtml" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html"&gt; &lt;h:head&gt; &lt;script type="text/javascript"&gt; var timeoutId = window.setInterval( "userClick()" , 1000 ); &lt;/script&gt; &lt;/h:head&gt; &lt;h:body&gt; &lt;h:panelGroup id="testo"&gt;test&lt;/h:panelGroup&gt; &lt;h:form prependId="false" &gt; &lt;h:commandButton id="buttonId" action="null" value="Invia"&gt; &lt;f:ajax event="click" execute="@form" render=":testo"/&gt; &lt;/h:commandButton&gt; &lt;/h:form&gt; &lt;script type="text/javascript"&gt; function userClick() { document.getElementById('buttonId').click(); } &lt;/script&gt; &lt;/h:body&gt; &lt;/html&gt; </code></pre> <hr> <p><strong>Update</strong>: After 1 days the application crash again. Now I have used only the setInterval but i have the heapDump generated by glassfish this is the screenshot but i'm unable to post it because my reputation is too low. however java.lang.Object[] consume 20% of heap, java.util.HashMap$Entry[]18% and HashMap 10% Any idea? </p> <p><strong>Update</strong>: Hi, guys i have solved my problem and have found a bug in CDI dependency/injection. I have solved my problem changing the Annotation @Named with @ManagedBean and this solve my problem. In the example i have omitted the code because i think that CDI haven't bug. Obviously the Bean annotated with @Named have request Scoped while the ApplicationScoped Bean doesn't produce the bug. I'm relatively new with CDI, so where i must report the bug?</p>

    2. COThis sends a request every second to the server, so you might want to look at how the request is handled. You might also want to up the interval timer, 1 second is very short considering the roundtrip might take longer than that.

    3. COIf I increase the interval the memory grow slowly but after some days the server crash in outOfMemory.Obviously the web page must be open in the browser.

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.
