    <p>Hey I've got a problem with fireing a change-event manually.</p> <p>So I have a selectOneMenu (i'ts like a dropdown in jsf) with different values.</p> <p>If I choose a value of this dropdown-list, a datatable should be updated. This works correctly, if i choose this value manually.</p> <p>Now there is a case, where I need to insert a new value to the selectOneMenu. This new value gets selected automatically, but the change-event to update the datatable doesn't get fired...</p> <p>So basically I have this button to save a new value to the selectOneMenu which then gets selected correctly, but the datatable doesn't get updated, which is why I tried to write the function fireChange() and gave that to the oncomplete of the button:</p> <pre><code>&lt;p:commandButton ajax="true" id="seatingPlanSave" actionListener="#{EventAssistentController.createSeatingPlan}" value="#{msg.save}" update=":createEvent:EventSeatingPlan, :createEvent:ticketTypePrices" oncomplete="fireChange()"/&gt; </code></pre> <p>For the fireChange()-function, i tried a few different things:</p> <pre><code>function fireChange() { var element = document.getElementById("createEvent:EventSeatingPlan_input"); element.change(); } function fireChange() { var element = document.getElementById("createEvent:EventSeatingPlan_input"); $(element).trigger("change"); } function fireChange() { if ("fireEvent" in element) element.fireEvent("onchange"); else { var evt = document.createEvent("HTMLEvents"); evt.initEvent("change", false, true); element.dispatchEvent(evt); } } </code></pre> <p>But none of these work :(</p> <p>Can you please tell me how I can achieve this?</p> <p>Thanks, Xera</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.
