[ https://issues.jboss.org/browse/CDI-114?page=com.atlassian.jira.plugin.sy... ] Vincent Massol commented on CDI-114: ------------------------------------ {quote} since xwiki is dynamic it needs to control what was injected before to be able to update which is not in Spring/Guice/CDI as basic features (always done through proxies and as an internal bean impl).{quote} In XWiki we do lazy instantiation of components, i.e. we instantiate them when they are required (ie. when the ComponentManager.getInstance() is called or when a component needs to be injected in another component). However we do not control what was injected before. FTR XWiki only supports field injection. Thus if you register a new implementation of a Component role at runtime, all existing components that have been instantiated already are not modified. However when a component needs to have an aways up to date @Inject(ed) field, we use a Provider<> and the code using it calls get() on it to return the latest registered component instance from the Component Manager. BTW thanks for your replies! :) -- This message was sent by Atlassian JIRA (v7.2.3#72005)
