Issue with "Find Artifact" : 'Unable to find a value for "versions" in object'

[JeremieB <je...@gmail.com>]

Hello,

It seems "Find artifact" feature of Archiva is broken for me, and I don't
know why... I know it used to work, but don't know if it doesn't anymore
since migrated to Archiva 1.2.2, or if some artifacts are causing it to
fail.

Symptoms :
- in "Find artifact"
- select a jar file (browse to it) in "search for"
- checksum gets calculated and is correctly displayed in "checksum" field
- clicking on search result in an internal server error (500), with
following (truncated) stacktrace :

javax.servlet.ServletException: Unable to find a value for "versions" in
object of class "org.apache.maven.archiva.model.ArchivaArtifact" using

I can provide full stack trace if needed.
Is it an Archiva issue ? If not, how can I investigate on my side ? (I have
a large number of artifacts in my repositories ...)

I'm using Archiva 1.2.2 on Linux RH4. I tried with different files as input,
still the same.

Thanks & regards,
Jeremie
