Method Detail
-
getLocalValue
Object getLocalValue()
Return the local value of this
UIComponent(if any), without evaluating any associatedValueExpression.
-
getValue
Object getValue()
Gets the value of this
UIComponent. If validation failed, as indicated byFacesContext.isValidationFailed()returningtrue, always return the local value. Otherwise, first, consult the local value property of this component. If non-nullreturn it. Ifnull, see if we have aValueExpressionfor thevalueproperty. If so, return the result of evaluating the property, otherwise returnnull. Note that because the specification forUIComponent.setValueBinding(java.lang.String, javax.faces.el.ValueBinding)requires a call through toUIComponent.setValueExpression(java.lang.String, javax.el.ValueExpression), legacy tags will continue to work.
