@SupportsInformalParameters
@Events(value="synchronizeValues")
public class Loop
extends Object

Basic looping class; loops over a number of items (provided by its source parameter), rendering its body for each one. It turns out that gettting the component to not store its state in the Form is very tricky and, in fact, a series of commands for starting and ending heartbeats, and advancing through the iterator, are still stored. For a non-volatile Loop inside the form, the Loop stores a series of commands that start and end heartbeats and store state (either as full objects when there the encoder parameter is not bound, or as client-side objects when there is an encoder). For a Loop that doesn't need to be aware of the enclosing Form (if any), the formState parameter should be bound to 'none'.

When the Loop is used inside a Form, it will generate an EventConstants.SYNCHRONIZE_VALUES event to inform its container what values were submitted and in what order.
