 IModel<? extends Collection<? extends T>> model,
 IOptionRenderer<T> renderer)

Method Details

setRecreateChoices

public SelectOptions<T> setRecreateChoices(boolean refresh)

Controls whether SelectOptions are recreated on each render.

Note: When recreating on each render, newOption(String, String, IModel) should return SelectOptions with stable values, i.e. SelectOption.getValue() should return a value based on its model object instead of the default auto index, otherwise the current selection will be lost on form errors.

Parameters:

refresh -

Returns:

this for chaining

See Also:

• SelectOption.getValue()

onPopulate

protected final void onPopulate()

Callback to let the repeater know it should populate itself with its items.

Overrides:

onPopulate in class RepeatingView

See Also:

• AbstractRepeater.onPopulate()

newOption

protected SelectOption<T> newOption(String id,
 String text,
 IModel<T> model)

Factory method for creating a new SelectOption. Override to add your own extensions, such as Ajax behaviors.

Parameters:

id - component id

text -

model -

Returns:

a SelectOption

onDetach

protected void onDetach()

Description copied from class: Component

Called to allow a component to detach resources after use. Overrides of this method MUST call the super implementation, the most logical place to do this is the last line of the override method.

Overrides:

onDetach in class MarkupContainer
