Redirect to the same page after performing different operations in Liferay? - liferay

Question

I have created a portlet in which i am doing CRUD Operations (User & Organization). But whenever I Add, Edit or Delete an Organization. I am redirect to the add user page after the operation. How can I stay on the same page after every operation ?
I tried using request dispatcher method and LastPath but couldn't make then work.
Now, I am using send redirect method which is working but whenever I signout and again signin this doesn't work (maybe because of Instance).
So how can i make this work properly please help.
Last Path Method Not Working.
HttpSession httpSession = httpServletRequest.getSession();
User user = UserLocalServiceUtil.fetchUser(UserId);
LastPath last_path = new LastPath("http://localhost:8080/web/my-site/one?p_p_id=my_registration_form_MyRegistrationFormPortlet_INSTANCE_HQMU9wIdWhH5&p_p_lifecycle=0&p_p_state=normal&p_p_mode=view&_my_registration_form_MyRegistrationFormPortlet_INSTANCE_HQMU9wIdWhH5_mvcPath=%2FaddOrganization.jsp"," ");
httpSession.setAttribute(WebKeys.LAST_PATH, last_path);
Working but have to set again after Signing out.
actionResponse.sendRedirect("http://localhost:8080/web/my-site/one?p_p_id=my_registration_form_MyRegistrationFormPortlet_INSTANCE_HQMU9wIdWhH5&p_p_lifecycle=0&p_p_state=normal&p_p_mode=view&_my_registration_form_MyRegistrationFormPortlet_INSTANCE_HQMU9wIdWhH5_mvcPath=%2FaddOrganization.jsp");
EDIT:
// For Adding Organizations
#ProcessAction(name = "addOrganization")
public void addOrganization(ActionRequest actionRequest, ActionResponse actionResponse) throws IOException, PortletException
{
long UserId = themeDisplay.getUserId();
String organizationName = ParamUtil.getString(actionRequest, "organizationName");
String country = ParamUtil.getString(actionRequest, "country");
String type = "organization";
long countryId = ParamUtil.getLong(actionRequest, "countryId");
long statusId = ParamUtil.getLong(actionRequest, "statusId");
try
{
Organization organization = OrganizationLocalServiceUtil.addOrganization(UserId, 0, organizationName, type, 0,countryId, 12017, null, false, null);
}
catch (Exception ex)
{
ex.printStackTrace();
}
}
In my view.jsp
<!-- For Displaying Add Organization Page -->
<portlet:renderURL var = "addOrganizations">
<portlet:param name = "mvcPath" value = "/addOrganization.jsp"/>
</portlet:renderURL>
In my addOrganization.jsp
<!-- For Displaying Add Organization Page -->
<portlet:renderURL var = "addOrganizations">
<portlet:param name = "mvcPath" value = "/addOrganization.jsp"/>
</portlet:renderURL>
<!-- For redirecting to the addOrganization method in MyRegistrationFormPortlet -->
<portlet:actionURL var = "addOrganization_actionURL">
<portlet:param name = "javax.portlet.action" value = "addOrganization"/>
</portlet:actionURL>
<form>
// my form
</form>

Ok I did quick checks and you can add the mvcPath as you do it for rendering directly in the actions.
#ProcessAction(name = "addOrganization")
public void addOrganization(ActionRequest actionRequest, ActionResponse actionResponse)
throws IOException, PortletException {
long UserId = themeDisplay.getUserId();
String organizationName = ParamUtil.getString(actionRequest, "organizationName");
String country = ParamUtil.getString(actionRequest, "country");
String type = "organization";
long countryId = ParamUtil.getLong(actionRequest, "countryId");
long statusId = ParamUtil.getLong(actionRequest, "statusId");
try {
Organization organization = OrganizationLocalServiceUtil.addOrganization(UserId, 0, organizationName, type,
0, countryId, 12017, null, false, null);
} catch (Exception ex) {
ex.printStackTrace();
}
actionResponse.getRenderParameters().setValue("mvcPath", "/addOrganization.jsp");
}

Are you using MVCActionCommands for this? Example for adding a user.
You can specify a mvcRenderCommandName parameter which will redirect to a render command. In the render command you can return a String with your jsp to call.
#Component(immediate = true, property = { "javax.portlet.name=" + PortletKeys.Test,
"mvc.command.name=/addUser" }, service = MVCActionCommand.class)
public class AddUserActionCommand implements MVCActionCommand {
#Override
public boolean processAction(ActionRequest actionRequest, ActionResponse actionResponse) throws PortletException {
//adding user to db logic
actionResponse.setRenderParameter("mvcRenderCommandName", "/users");
return false;
}
}
RenderCommand
#Component(immediate = true, property = { "javax.portlet.name=" + PortletKeys.Test,
"mvc.command.name=/users" }, service = MVCRenderCommand.class)
public class UserRenderCommand implements MVCRenderCommand {
#Override
public String render(RenderRequest renderRequest, RenderResponse renderResponse) throws PortletException {
//doing some stuff
return "/users/view.jsp";
}
}
Just be sure that the annotation "mvc.command.name" matches the render parameter which you set in "mvcRenderCommandName".

As I wrote in my first answer I would recommend to split the actions in own classes. If you try to put everything into the Portlet class you can try to include a jsp with the include() method. This is how we did that in 6.2 but I see include() is still available in 7.x.
// For Adding Organizations
#ProcessAction(name = "addOrganization")
public void addOrganization(ActionRequest actionRequest, ActionResponse actionResponse) throws IOException, PortletException
{
long UserId = themeDisplay.getUserId();
String organizationName = ParamUtil.getString(actionRequest, "organizationName");
String country = ParamUtil.getString(actionRequest, "country");
String type = "organization";
long countryId = ParamUtil.getLong(actionRequest, "countryId");
long statusId = ParamUtil.getLong(actionRequest, "statusId");
try
{
Organization organization = OrganizationLocalServiceUtil.addOrganization(UserId, 0, organizationName, type, 0,countryId, 12017, null, false, null);
}
catch (Exception ex)
{
ex.printStackTrace();
}
include('/html/myJsp.jsp',actionRequest,actionResponse);
}
