I am using Liferay 6 for the Portal Development .
By going through Liferay developer Guide the author explains that there are Two phases of Portlet Execution
Action Phase
Render Phase
public class DateTimePortlet extends GenericPortlet {
public void doView(RenderRequest req, RenderResponse res) throws IOException, PortletException {
Object actionAttribute = req.getAttribute("datetime");
res.getWriter().println("Date Time:" + (actionAttribute != null ? actionAttribute :"Unavailable"));
res.getWriter().println("<BR/>");
PortletURL u = res.createActionURL();
res.getWriter().println("<A href=" + u + ">Trigger an action.");
res.getWriter().close();
}
public void processAction(ActionRequest req, ActionResponse res) throws PortletException {
req.setAttribute("datetime",new Date());
}
}
What my understanding is that , the doView method is known as Render Phase and the processAction Method is known as Action Phase . And if there are 5 portlets displayed on a page , the Render Phase (That is the code inside the doView Method) is executed for every Page refresh ??
Please let me know if i am correct ??
