Querying for bean references

[Nigel Sim <ni...@gmail.com>]

Hi,

I would like to compose a query to find all nodes which have a reference to
another bean. ie:
Class Image:
  Camera camera
  InputStream data

Class Camera:
  String someInfo
  String type

So I would like to find all Image where camera is camera (or camera uuid).
I'm using the OCM bindings, and query language.

The follow on question is, can I do joins, like find all images where the
camera type = X

I've looked through the docs and API as best as I could, and I feel that the
JCR Expression might be what I need, but I didn't find any specific
documentation on this feature.

Cheers
Nigel

Hi Nigel,
This kind of query (based on Bean fields) is not yet supported in OCM.
