Customize CreateAccountAction in Liferay Portal

Question

I'm trying to add "User Group" Selection field while creating a user (Self User Registration form - create_account.jsp). Here Custom fields is not helpful because Usergroup is already exists in db. I want to insert into existing Users_UserGroups table. I'm using below hook: But User is not added in the group and no exception is printed.

Please suggest me for any other way to achieve this.

public class CustomCreateAccountAction extends BaseStrutsPortletAction
{ 
    public void processAction(StrutsPortletAction originalStrutsPortletAction, PortletConfig portletConfig, ActionRequest actionRequest, ActionResponse actionResponse) 
                    throws Exception 
            { 
                System.out.println("My Custom Process Action Method is Called"); 

                String emailid=ParamUtil.getString(actionRequest, "emailAddress");
                long[] userGroupIds = null;

                originalStrutsPortletAction.processAction(originalStrutsPortletAction, portletConfig, actionRequest,actionResponse); 

                System.out.println("This is after user is registered");
                if (SessionErrors.isEmpty(actionRequest)) 
                {
                ThemeDisplay themeDisplay =(ThemeDisplay)actionRequest.getAttribute(WebKeys.THEME_DISPLAY);

                long newlyCreatedUserId=UserLocalServiceUtil.getUserIdByEmailAddress(themeDisplay.getCompanyId(), emailid);

                long userIds[]={newlyCreatedUserId};
                long dummygroupid=16206;

                System.out.println("TEST UserID="+newlyCreatedUserId);
                System.out.println("TEST GroupID="+dummygroupid);
                //Everything went well until here.
                UserServiceUtil.addUserGroupUsers(dummygroupid, userIds);
                //below sysout is not printed. and no exception or user in group db created. 
                System.out.println("user added to group");
                }

            } 


            public String render(StrutsPortletAction originalStrutsPortletAction, PortletConfig portletConfig, RenderRequest renderRequest, RenderResponse renderResponse) throws Exception 
            { 
                System.out.println("My Custom Render Method is Called"); 
                return originalStrutsPortletAction.render(null, portletConfig, renderRequest, renderResponse);   
                } 

        } 

for more info please have a look at this thread.

Answer 1

Using UserLocalServiceUtil instead of UserServiceUtil worked. Basically, the difference is that *ServiceUtil checks permissions and *LocalServiceUtil does not.
