renderView

public void renderView(javax.faces.context.FacesContext context,
                       javax.faces.component.UIViewRoot viewToRender)
                throws IOException,
                       javax.faces.FacesException

Overrides:

renderView in class javax.faces.application.ViewHandlerWrapper

Throws:

IOException

javax.faces.FacesException

evaluateExpressionJSF1

protected String evaluateExpressionJSF1(javax.faces.context.FacesContext facesContext,
                                        String viewId)

Mojarra 1.x does not have the ability to process faces-config navigation-rule entries with to-view-id containing EL-expressions. This method compensates for that shortcoming by evaluating the EL-expression that may be present in the specified viewId.

Parameters:

facesContext - The current FacesContext.

viewId - The viewId that may contain an EL expression.

Returns:

If an EL-expression was present in the specified viewId, then returns the evaluated expression. Otherwise, returns the specified viewId unchanged.

getRedirectURL

public String getRedirectURL(javax.faces.context.FacesContext facesContext,
                             String viewId,
                             Map<String,List<String>> parameters,
                             boolean includeViewParams)

Overrides:

getRedirectURL in class javax.faces.application.ViewHandlerWrapper
