Bug: when user adds new currency to existing gateway, does not show in client

[bekkibolthouse]

User kwelstr reported over IRC and via stellartalk:

User added new currency to existing trusted gateway, but new currency did not show in client. API gave expected response, as did /viewer. Workaround: remove trust lines to gateway, add trust anew.

This appears to be a bug with the way the client displays currencies for a particular gateway. Reference: https://stellartalk.org/topic/6853-dividendrippler-now-supporting-stellar/#entry69270

Ok I've taken a look a this while writing tests for the add-gateway, gateway-list and gateway-list-item controllers and couldn't find any blatant bug in those.

From reading the entry on stellartalk it seems clear the user added the currency via the API, not the client, so maybe something goes wrong when the wallet is loaded upon login by the client.

Could be somewhere in the session or Wallet services, haven't had time to dive too much into these yet...

I was reading the stellartalk thread again and realized I didn't get it the first time around: the user had opened lines to a gateway which then aded support for another currency. Support for that currency was not reflected in the client UI (in the list of currencies supported by the gateway), unless the user would remove and re-open the lines.

It reads like the user tried opening the client in several browsers so if the problem persisted across opening/closing sessions I'd say it's not in the client code, since the wallet seems to be re-loaded for every session.
