Re: Property with Multiple References

[Felix Meschberger <fm...@gmail.com>]

[Moving to dev]

It looks like the problem is at line #103 in the JsonResourceWriter
class of the Default GET Servlet bundle. This adapts the resource to a
single string value, which is not implemented very stable in the
JcrPropertyResource.adaptTo method: It just calls Property.getString(),
which throws for a Multi-Value property.

Probably we should replace this by adapting to String[] and then either
set the result to an array of values or a single value.

WDYT ?

Yet, lets wait for the issue report ;-)
