Hello,

We are migrating portlets from Liferay 6.2 to Liferay 7.3 but it seems the model from rendermapping phase it isn't the same than in actionmapping phase 

My code is:

@Controller
@SessionAttributes(types = { String.class, Locale.class, List.class, HashMap.class })
@RequestMapping("VIEW")
public class ControladorPortlet {

    @RenderMapping
    public String entrada(RenderRequest request,Map<String, Object> modeloPagina, RenderResponse resp) {
                modeloPagina.put("OPERATION", "1");
                //.............................................
                return "VISTA";

    }

    @ActionMapping(params = "accion=continuar")
    public void nuevaPagina(PortletRequest portletReq, Map<String, Object> modeloPagina,ActionRequest request,
            ActionResponse response) {        
          
        //Here modeloPagina is empty  and we expect to have the field OPERATION
            
    //        
}

In liferay 6.2 we had spring 4.0 and now we have spring 5.0

Do you see anything that I may have missed? Any help would be much appreciated.

SOLVED: It is a bug in portletmvc4spring, 7.2.1 version. https://issues.liferay.com/browse/MVCS-37
