I was pretty sure at the time I created it, that there was a validation
of this in one of our sample apps... It had worked at one point :)
It is entirely possible that the CBOR conversion ended up breaking this.
Can you file a JIRA ticket at JIRA.iotivity.org and include this info?
Particularly any DIFFs that you did to cause this.
The bad-get error is usually because the parsed type doesn't match the
fetched type (so trying to assign an int to a string or something).
the correct way to get the value out should be something like:
std::vector<std::vector<int>> myvector = rep["power"];
If this doesn't work, it is almost definitely a bug.
Thanks,
Erich
