Description Heiko Böttger

In our plugin we calculate the ContentType based on metadata. Since metadata may change without changing the file pointing to the metadata, the contenttype is never recalculated. There is a public method "invalidateCache" but no way to reach it. It seems like there is no support for a ContentDescription/ContentType Change Notification.

Renaming as a feature request as this is not exactly a bug.

In general, it seems to me that what you're doing is wrong regarding the concept of a content-type. A content-type should be only related to file name and file content. If you need some other things to sort out a content-type, then it means what you're dealing with isn't really a content-type but another concept which is specific of yours.
Let's keep this bug open for some time, but given that the user-story behind it seems to not be a "clean" one, we'll probably end up marking this one as WONTFIX.
