  • State changed from “new” to “open”
  • Assigned user changed from “Jonathan Lister” to “Ben Hood”
  • Milestone order changed from “35” to “0”

  If the URL of the participants is on another domain (or port), the participants will need to support JSONP for getting the content.

  I have the interface doing what it can to get the content, but it can't access cross-domain stuff.

  Sorry, I don't understand this: ATM the agent is proxying the call to the participants so I don't see the x-domain implication. BTW this is already working (i.e. the diagnostic box is correctly populated with the content that the demo participant set) for me, so I am a bit confused.

  Jonathan, I'm assigning this back to you to denote the fact that next question is for you :-)

  I might be getting the URL for the content-getting from the wrong place, but I think it is from /config/pairs/${id}.

  In this picture, you see the upstream and downstream 'url' parameters pointing to hosts that are on a different port to the agent: http://img.skitch.com/20101008-bja4h8j16at83fpg4xce6bppfg.jpg

  You said it was working for you, so I'm a bit unsure how your browser is doing the x-domain thing.

  The call to get the content detail is this one:

  http://diffa.lshift.net/doc/rest/diffs/get/events/p_sessionId/p_evt...

  The UI does a GET on the agent, who, in turn, proxies the actual request out to the individual participants. This is completely transparent to the client, so there is no x-domain issue. Please get in contact with me tomorrow to clarify this because I can see us misunderstanding each via Lighthouse.

  I see! I was using the wrong URL... thanks.

  I have noticed that the response from the server is only "Expanded Detail" - this should send something for each of the upstream and downstream participants. How about:

  {"upstream":"Expanded Detail for upstream","downstream":"Expanded Detail for downstream"}

  (from [e09b4bbdc1426bf59ee2ca3119b5ce1ae4a35d24]) Getting content from server rather than trying cross-domain requests to participants

  [[#100]] http://github.com/lshift/diffa/commit/e09b4bbdc1426bf59ee2ca3119b5c...

  • State changed from “open” to “closed”

  Yes, you're right - ATM the server is only returning a hard coded string "Expanded detail" (see ticket #6 for background). So the call you are currently making is correct, hence this issue can be closed. For note, please see ticket #127 which is related to this issue.

  Jonathan - I've plumbed through a little of #6 so that the upstream is being set correctly (i.e. dynamically), but the UI seems to be sending the same for the downstream as well - note that I haven't looked into this in detail yet. Do you have any ideas off the top of your head?

  As you've pointed out, the interface needs to discriminate between the two participants. I'll make the future notes on #6.
