    <p>This is my first time asking a question on a forum, since usually my questions have already been asked and answered. I haven't found an answer to this problem that works for me, so here goes:</p> <p>I'm making an Ajax call in JSF 2.0 like this:</p> <pre><code>&lt; f :ajax listener="#{myReferenceController.clearRequiredReferenceNumber}" onevent="resetFocus" execute="@form" render=":resultsForm:ResultsDisplay" /&gt; </code></pre> <p>Everything in the listener works perfectly, and the data is then rendered as expected in the data table that I have in my .xhtml page. The problem is that the Javascript that I call in the <code>onevent</code> seems to be getting called before the rendering is complete, and therefore the process of resetting the focus to a column in my <code>datatable</code> doesn't work, since the <code>datatable</code> is removed and then re-added to the DOM when the Ajax is finished re-rendering. </p> <p>I'm looking in my Javascript for the status of "success", in hopes that at this point, the rendering would have completed. Alas, this is not the case, and my <code>getElementById</code> (actually <code>dojo.byId</code>) is not finding the element in the datatable. I know my Javascript function works under normal circumstances, since I'm calling this same function in a situation where there is not an Ajax call, and everything works perfectly there.</p> <p>If I could just avoid rendering the cell in the table that I'm trying to set focus to, that would be great, but my listener is making changes to this cell in the ajax call. I'm at my wits end, so any ideas on this would be very appreciated.</p> <p>-- in response to Balusc (heard good things about you, btw)</p> <p>Hmm, I was actually on the right track I think, but still seem to be having troubles. I am checking for "success" and still even in success, am not able to set the focus here. Here's my Javascript function that is checking for "success": This function works in another situation, where it's not attached to an Ajax event.</p> <pre><code>function resetFocus(data) { var theRow = dojo.byId("resultsForm:selectedRow").value; if (data.status == "success") { dojo.query('[widgetId]',dojo.byId('theResultsDataTable')) .forEach(function(node) { var widget = dijit.byNode(node); var theId = widget.attr("id") if (theId.indexOf(':' + theRow + ':') != -1) { if (theId.indexOf('theOrppoNum') != -1) { widget.focus(); widget.attr("isFocused",true); } } }); } } </code></pre>

    1. COThis looks like an `oncomplete` javascript method for your ajax request. Sadly, this method is not in the JSF specification (more info about it [here](http://old.nabble.com/Is-there-any-'oncomplete'-method-in-jsf.ajax.request()--td28025156.html)). Alternatively, you could use [PrimeFaces](http://www.primefaces.org/showcase-labs/ui/ajaxifyKeyEvents.jsf) or [RichFaces](http://showcase.richfaces.org/richfaces/component-sample.jsf?demo=ajax&skin=blueSky), these frameworks handle this `oncomplete` method for ajax requests.

    2. COIf this oncomplete method simply handles the attribute status that the event listener gets passed, I don't think this will help me. Even the "success" status seems to be coming back before the ajax and jsf is finished rendering. I'll look into the prime faces and richfaces avenues though.....

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.
