Programmatically disclosing a ShowDetailItem in a <af:panelTabbed>

In this post I'm sharing an example illustrating the programmatic disclosure of <af:showDetailItem> which is added inside a <af:panelTabbed>. Please note that while programmatically disclosing a showDetailItem, it's your responsibility to set the 'Disclosed' to false for the previously displayed item. To illustrate this, take a look at the following code snippet:

RichPanelTabbed richPanelTabbed = getPanelTabbed();
for (UIComponent child : richPanelTabbed.getChildren()) {
    RichShowDetailItem sdi = (RichShowDetailItem)child;
    sdi.setDisclosed(isThisItemToBeDisclosed(sdi));
}
