Description

because 'javax.view.id' will not be find in request.getParametersMap, the restore phase executor will stop execute.

source code:
package org.apache.myfaces.lifecycle;
.........
class RestoreViewExecutor implements PhaseExecutor
..........
public boolean execute(FacesContext facesContext){
..................

if (!errorPageRequest && restoreViewSupport.isPostback(facesContext))

{ ................ }

...............
}

restoreViewSupport.isPostback(facesContext) will call facesContext.getExternalContext().getRequestParameterMap().get(ResponseStateManager.VIEW_STATE_PARAM)

but request.parameterMap is empty because of using 'multipart/form-data'.

restoreViewSupport.isPostback(facesContext) will return false,

then FacesContext.renderResponse() is called. the whole phasing process is stopped.

suggestion:

should wrap request.parameterMap from the first place.
