Setting value through EL in JSF

Sample method can be used to set new object programmatically:

public static void setObject(String expression, Object newValue) {
FacesContext facesContext = getFacesContext();
Application app = facesContext.getApplication();
ExpressionFactory elFactory = app.getExpressionFactory();
ELContext elContext = facesContext.getELContext();
ValueExpression valueExp =
elFactory.createValueExpression(elContext, expression,
Object.class);

//Check that the input newValue can be cast to the property type
//expected by the managed bean.
//Rely on Auto-Unboxing if the managed Bean expects a primitive
Class bindClass = valueExp.getType(elContext);
if (bindClass.isPrimitive() || bindClass.isInstance(newValue)) {
valueExp.setValue(elContext, newValue);
}
}
