Changeset 1473 for ComponentRegistry/trunk/ComponentBrowserGui/src/main/flex/clarin/cmdi/componentregistry/editor/EditorAS.as

Message:

GUI: implemented ComponentUsageService?, which calls the component/usage/ (see @1462-@1465) service to check whether the specified component is in use.
It is called when updating private components. Currently, the service response is not being processed so the event will always tell the component is in use.
