When using local charms, the URL used to retrieve charm info is not correct

[Francesco Banconi]

From the Javascript console of Juju GUI deployed using the charm:

XMLHttpRequest cannot load https://jujucharms.com/charms/precise/juju-gui-17/json. Origin https://ec2-23-22-109-54.compute-1.amazonaws.com is not allowed by Access-Control-Allow-Origin.

It is possible to see this error when trying to retrieve charm info, i.e. going to the Juju GUI service detail, and clicking the "charm" tab.

According to hazmat on IRC, the right link for the Juju GUI charm right now is https://jujucharms.com/~juju-gui/precise/juju-gui/json .

@teknico that's correct but not pertinent AFAICT. Francesco deployed the GUI charm from a local repo, he said. Some code somewhere appears to be guessing that it knows how to create a charm store URL from a local charm. That's a pretty dangerous guess, I think. There's no way to know. I *think* that's what we need to address, but we should try to dupe this and get more information.

The problem happens when deploying local charms as per the HACKING doc. In that case the charm owner is not set, and the jujucharms.com charm URL is computed incorrectly. It looks like there is no easy fix for this, and we will overhaul the charm tab in the service view page anyway, as per bug #1074278, so we (Gary and I) decided that it's not worth it to spend significant time on fixing this.
