Restaurer soi-même une view

Voilà ma façon de faire. Il faut utiliser JSF sun RI (1.2_8) et richfaces (3.3.1)

Dans un PhaseListener apres la phase "render view":

Code:

1
2
3
4
5
6
7
8
 
ExternalContext externalContext = event.getFacesContext().getExternalContext();
 
//caution : RichFaces specific
Object viewSeq = externalContext.getRequestMap().get(AjaxStateManager.VIEW_SEQUENCE);
if (viewSeq != null){
	externalContext.getSessionMap().put(LAST_VIEW_STATE, viewSeq);
}

puis dans un phase listener "before restore view":

Code:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
22
23
 
ExternalContext extCtx = facesCtx.getExternalContext();
 
boolean postback = !extCtx.getRequestParameterMap().isEmpty()
                                    &&  extCtx.getRequestParameterMap().containsKey(ResponseStateManager.VIEW_STATE_PARAM);
if (!postback){
            	// mus be a GET
            	Object request = extCtx.getRequest();
            	if (request instanceof HttpServletRequest) {
            		String viewId = ((HttpServletRequest) request).getServletPath();
 
	                Object viewState = extCtx.getSessionMap().get(LAST_VIEW_STATE);
 
            if (viewState != null){
            	//caution: JSF Sun RI specific
        	RequestStateManager.set(facesCtx,
		                     RequestStateManager.FACES_VIEW_STRUCTURE, viewState);
 
 
facesCtx.getApplication().getViewHandler().restoreView(facesCtx, viewId);
        }
    }
}
