Having problems with dynamic Asset folders and {owner.slug} I have a Matrix field with four blocks currently, a header (text), explanation (rich text), slideshow (assets), and single image (assets). Both the slideshow and single image blocks have two fields, image and caption.

The image field is the same in both with the exception of the slideshow assets field allows multiple images to be uploaded while the single is obviously limited to one. Both have "Restrict uploads to a single folder?" and "Restrict allowed file types?" checked and the latter only allows images. Both also have the same Asset Location selected and {owner.slug} as the path. Recently I discovered that I can no longer upload images to {owner.slug}, instead Craft is trying to upload images to /craft/storage/runtime/assets/tempuploads/field_##.

I've checked file permissions for my assets directory and there shouldn't be a problem writing to it. I used to be able to create subfolders based on the entry slug and what's even more bizarre is that I can edit an existing single image or slideshow block image field and it will use/upload to the proper directory.

Any ideas why it would stop doing this?
According to Andris this is the expected behavior in this situation. The bug fix does make Craft work as intended but creates a slightly confusing workflow if you don't know what to expect. The good news is my expected behavior, which is to have assets available if {owner.slug} has been created in my assets folder already, is on the official list of features to implement. Well, assuming Andris doesn't go into a drunken stupor and forget to tell Brad or Brandon.
