AbstractComponentConnector
You should typically not override this method since the framework by
default generates an implementation that uses GWT.create(Class)
to create a widget of the same type as returned by the most specific
override of AbstractComponentConnector.getWidget(). If you do override the method, you
can't call super.createWidget() since the metadata needed
for that implementation is not generated if there's an override of the
method.

HasComponentsConnectorEach 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.

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.
