Initial Value
|
The value to which the visual component is initialized upon its instantiation. Note, this value will overwrite any value in the bound model field if one exists. If you want to set a value on a component without potentially overwriting the model field's value, avoid using this property and instead use the setValue(Object value,boolean overwrite) method with the overwrite parameter set to false. You may call this method from your code as needed (for example, from an event handler) or from the Post-initialization Code property of the component.
