Hi,

I'm trying to use portlet MVC annotation based, but I get some trouble if I want to use @ActionMapping !
in my jsp I've got :
Code:
...
<portlet:defineObjects/>
<portlet:actionURL name="showClientForm" var="clientFormUrl"/>

<a href="${clientFormUrl}">add client</a>
...
In my controller :
Code:
...
        @ActionMapping("showClientForm")
	public String goToForm(Model model) {
		log.info("method goToForm");
		model.addAttribute("client", new ClientImpl());
		return "formClient";
	}
When I click on the link from the jsp, goToForm method is called, but it fail to show the view with the following error :
Code:
16:03:15,751 ERROR [DispatcherPortlet:559] Could not complete request
java.lang.IllegalStateException: Invalid action method return value: ModelAndView: reference to view with name 'formClient'; model is {client={clientId=0, companyId=0, userId=0, userName=, createDate=null, modifiedDate=null, firstName=, lastName=}, org.springframework.validation.BindingResult.client=org.springframework.validation.BeanPropertyBindingResult: 0 errors}

How to solve that ?

I'm using Liferay 6.0.6 and my application is deployed with the plugin SDK.
