Asiri, is webdav servlet use Utils.prepareContext to create/prepare the context ? (the Utils's ComponentManager is initialized in it)
Previously we used a small workaround for a problem we encountered with component manager as follows,
In Utils.prepareContext() method we had a problem where the component manager is null ... so we did,
ComponentManager componentManager = (ComponentManager) engine_context.getAttribute(ComponentManager.class.getName());
+ if(null != componentManager) { + context.put(ComponentManager.class.getName(), componentManager); + }
You also have to call static Utils.setComponentManager(componentManager) to init Utils ComponentManager.
How can i initialize the componentManager (to pass into above method) ?
Sorry about asking too much questions, kind of away from my build environment, no way to test till tomorrow.
Thanks.

Utils.getComponent("component") does not use the context's ComponentManager anymore to be able to get component whithout context.
This worked fine untill recently. But I think now we have to handle this issue. The main problem is,
ComponentManager componentManager = (ComponentManager) engine_context.getAttribute(ComponentManager.class.getName());
Here, componentManager becomes null. What could be the reason for this ?
I look in sandbox this time and I think the problem is that ComponentManager is not created and inserted in engine_context so when prepareContext ask for it it get a null value and give it to Utils. You should look in shared-test project (/trunks/xwiki-platform-tools/xwiki-shared-tests/src/main/java/com/xpn/xwiki/test/AbstractXWikiComponentTestCase#getComponentManager()) to see how to create one. Then insert it in the "engine" (XWikiServletContext here) argument before calling prepareContext. I can do it directly in xwiki-webdav and commit in sandbox if you want.
Thanks a lot.

PS : Previously vincent said not to use this workaround but we used it
since
it worked.

ok, I think the problem is that when the first connection is webdav ComponentManager is not initialized in Utils
