How to add nested portlets (liferay) through code

Question

We have something called nested portlets in liferay. I want to add this portlet dynamically using code. Does anyone know the code to add nested portlets and add other portlets to it?

Thank!!!

for a complete example, I assume that you want to add a nested portlet to the current page using a different portlet action handler. (if you use from the render action, you will not see the attached portlet until the next page view)

Add these methods to your code

private static String addPortlet(final long p_userId, final Layout p_layout, final String p_portletId, final String p_columnId, final int p_position, final boolean p_checkPermission)
                throws PortalException, SystemException
{
    if (p_layout.isTypePortlet()) {
        final LayoutTypePortlet layoutTypePortlet = (LayoutTypePortlet) p_layout.getLayoutType();

        final String portletId = layoutTypePortlet.addPortletId(p_userId, p_portletId, p_columnId, p_position, p_checkPermission);
        if (portletId != null) {
            final String rootPortletId = PortletConstants.getRootPortletId(portletId);
            final String portletPrimaryKey = PortletPermissionUtil.getPrimaryKey(p_layout.getPlid(), portletId);
            ResourceLocalServiceUtil.addResources(p_layout.getCompanyId(), p_layout.getGroupId(), 0, rootPortletId, portletPrimaryKey, true, true, true);
            LayoutLocalServiceUtil.updateLayout(p_layout.getGroupId(), p_layout.isPrivateLayout(), p_layout.getLayoutId(), p_layout.getTypeSettings());
        }
        return portletId;
    }

    return null;
}

private static void addNestedPortlet(final PortletRequest p_request) throws PortalException, SystemException {
    final ThemeDisplay themeDisplay = (ThemeDisplay) p_request.getAttribute(WebKeys.THEME_DISPLAY);
    final Layout layout = themeDisplay.getLayout();
    long userId = themeDisplay.getUserId();

    //create nested portlet and add it to "column-1"
    final String nestedPortletId = addPortlet(userId, layout, "118", "column-1", -1, false);

    //this will be used to target nested portlet columns
    final String nestedColumnPrefix = "_" + nestedPortletId + "__";

    //default page layout (used by nested portlet) has two columns
    //we'll add two portlets (in this example two iframe portlets), one portlet to each column
    addPortlet(userId, layout, "48", nestedColumnPrefix + "column-1", -1, false);
    addPortlet(userId, layout, "48", nestedColumnPrefix + "column-2", -1, false);
}
