Hi Yoshiaki,

Marios asked me to look at this.
I have discussed it with him.
Can you describe the problem you are trying to address?

State is included with the instance operation, not with the instances
operation.
The specification for the instances operation is that it may not
retrieve as much detail as the instance operation does.
Due to the way state needs to be retrieved from the FGCP API backend
(i.e. a separate call for each instance), I found that with my contract
of several systems and instances, it takes so long for the operation to
complete when using the UI that the browser times out.
Hence the reason to exclude state (and any other details such as
credentials and public ip addresses that require additional calls) from
the instances operation.

I am not familiar with the ruby client's Stateful Object and I wonder if
it assumes state is returned by the instances method, if it's the ruby
client that needs to be patched. Could you provide more details?

Thanks,
Dies Koper
