As it appears in the showcase, the selectManyCheckBox doest not allow the user to select multiple values:

Code: Select all

                    <h:selectManyCheckbox id="checkbox">
                        <f:selectItem itemLabel="Option 1" itemValue="Option 1" />
                        <f:selectItem itemLabel="Option 2" itemValue="Option 2" />
                        <f:selectItem itemLabel="Option 3" itemValue="Option 3" />
                    </h:selectManyCheckbox>
