Error when saving datastream

[jcoyne]

On Alpha 4, when I POST an XML document to: http://localhost:8983/fedora/rest/ad/da/87/89/adda8789-ab2a-44f8-be67-8f57fd4e5fb3/descMetadata/fcr:content

I get a 500 response with this body:

javax.jcr.nodetype.ConstraintViolationException: Unable to determine a valid node definition for the node "/ad/da/87/89/adda8789-ab2a-44f8-be67-8f57fd4e5fb3/descMetadata/19" in workspace "default" of "repo"

It seems to occur when I post content to the same URL twice in a row. The first response is a 201, the second is a 500

[jcoyne]

It seems that using a PUT works just fine, but the error when using POST is unclear and maybe unnecessary.

[escowles]

Yes, in general, POST is for creating new resources and PUT/PATCH is for modifying them.

I think the 500 error is because it's trying to create a child resource under the datastream, so it's getting an error trying to figure out which type to create because there aren't any valid types. I've opened a Pivotal ticket for fixing this bug and returning a 4xx error when trying to POST to an existing fcr:content node: https://www.pivotaltracker.com/story/show/69610980
