[TYPO3-dam] Not able to assign a category to a image file

[Gideon So]

Hi,

	I am just able to index the files in a directory. I can see them with
the media>list module. Then I try to edit the file and assign a category
(recently add with the media>category module) to it. After I save,
there's no category in the field. What's wrong??
