[xwiki-devs] [GSOC][WEBDAV] Problem With Core Failing (XWikiCacheStore)

[Asiri Rathnayake]

Hi All,

I cannot test xwiki-webdav anymore because XWikiCacheStore throws a null
pointer exception that i cannot figure out. I think this is introduced by a
recent commit, please help me with this. Following is the exception,

</dump>

In XWikiCacheStore.initCache() method,

CacheFactory cacheFactory = context.getWiki().getCacheFactory();

here, cacheFactory has become null.

I've only found this problem and currently looking into it, if anyone can
help me get over this quickly it would be a big help.

Thanks.
