Method Detail

createView

public javax.faces.component.UIViewRoot createView(javax.faces.context.FacesContext facesContext,
                                                   String viewId)

The purpose of overriding this method is to work-around a problem in the Mojarra com.sun.faces.application.view.MultiViewHanderl#derivePhysicalViewId(FacesContext, String, boolean) method. Specifically, the method does not expect a query-string (like ?javax.portlet.faces.PortletMode=edit) in the viewId. This is expected actually, because the JSF spec does not provide for query-strings. However, it is indeed a Bridge Spec feature. This method temporarily removes the query-string before asking Mojarra to create the view, and then adds it back.

Overrides:

createView in class javax.faces.application.ViewHandlerWrapper

restoreView

public javax.faces.component.UIViewRoot restoreView(javax.faces.context.FacesContext facesContext,
                                                    String viewId)

Overrides:

restoreView in class javax.faces.application.ViewHandlerWrapper

getActionURL

public String getActionURL(javax.faces.context.FacesContext facesContext,
                           String viewId)

The purpose of this method is to provide a workaround for an incompatibility with the Mojarra implementation of JSF. Specifically, the Mojarra com.sun.faces.application.view.MultiViewHandler#getActionURL(FacesContext, String) method does not properly handle viewId values that contain dot characters as part of the query-string. For example, if the specified viewId is "/view.xhtml?javax.portlet.faces.PortletMode=edit" then Mojarra will think the filename extension is ".PortletMode" instead of ".xhtml". This method works around the problem by temporarily substituting all dot characters in the viewId query-string with a token before delegating to the Mojarra method. After delegation, the dot characters are replaced.

Overrides:

getActionURL in class javax.faces.application.ViewHandlerWrapper

getWrapped

public javax.faces.application.ViewHandler getWrapped()

Specified by:

getWrapped in interface javax.faces.FacesWrapper<javax.faces.application.ViewHandler>

Overrides:

getWrapped in class javax.faces.application.ViewHandlerWrapper
