The selected deserts from the list, are shown in the
<tc:out id="desertOutput" .../>
.
The value in the output field will be rerendered, after the selection in the list changed. For that,
<tc:selectManyListbox label="Deserts" size="4" ...>
contain a
<f:ajax render="desertOutput"/>
tag.
The number of rows is set to four by the size
attribute. Is no size set, the height of the list
depends of the number of rows. The list shows at least two rows. Values lower than two have no effect.
