Method Detail

evalAttribute

public static Object evalAttribute(UIComponent component,
                                   String name)

Evaluates an attribute of a component by first checking if there's a value expression associated with it, and only if there isn't one look at a component property with that name.

The regular attribute collection (UIComponent.getAttributes()) does exactly the reverse; it looks at a component property first, then at the attribute collection and only looks at a value binding as the last option.

Parameters:

component - The component for which the attribute is to be evaluated

name - Name of attribute that is to be evaluated

Returns:

The value of the attribute, or null if either the component is null or if there's isn't an attribute by that name
