public void updateCaption(ComponentConnector childConnector)
HasComponentsConnector
Each component is responsible for maintaining its caption, description and error message. In most cases components doesn't want to do that and those elements reside outside of the component. Because of this layouts must provide service for it's childen to show those elements for them.

public void postLayout()
PostLayoutListener
LayoutManager
to notify the connector that a
layout phase has ended. This method can be used to finalize internal
layouting, but it is not allowed to change the its own external size or
modify the conditions for any children.postLayout

public void onConnectorHierarchyChange(ConnectorHierarchyChangeEvent connectorHierarchyChangeEvent)
ConnectorHierarchyChangeEvent.ConnectorHierarchyChangeHandler
This method is called after the shared state and hierarchy data (i.e.
AbstractHasComponentsConnector.setChildComponents(List)
) been
updated for all affected connectors, but before updating captions,
firing state change events, invoking updateFromUIDL for legacy
connectors, invoking RPC and starting the layout phase.
Please note that hierarchy change events are fired in a non-deterministic order when a message from the server causes multiple parts of the hierarchy to change. This means that the old parent connector might not yet have detached a child widget and that the widget of a removed child might already have been attached by its new parent.
