2.5.3
> Shindig's RPC mechanism assumes that the container page and container script
> exist within the same window

> Key: SHINDIG-1553
> URL: https://issues.apache.org/jira/browse/SHINDIG-1553
> Project: Shindig
> Issue Type: Bug
> Components: Javascript
> Affects Versions: 2.0.2
> Reporter: Stanton Sievers
> Labels: rpc
> Fix For: 2.5.3
>
>
> The primary use case that this bug precludes is one in which the container.js
> script (and subsequently rpc.js) are loaded in a separate frame than the main
> content page, i.e., the page that contains the gadget iframes.
> Imagine a main page consisting of a frameset with two frames: ContentFrame
> and ScriptFrame. ScriptFrame loads the container JavaScript. It includes
> the script tag whose src equals
> "http://<myserver>/gadgets/js/container:rpc.js". ContentFrame references the
> global namespaces in ScriptFrame (gadgets and osapi) to instantiate an
> osapi.container.Container object. The page then creates a GadgetSite giving
> it a div that exists within ContentFrame. Then navigateGadget is called on
> the container.
> The use case above will break outright because rpc.js makes the assumption
> that the ScriptFrame and ContentFrame are one and the same. For instance, in
> rpc.js, setupChildIframe() uses document.getElementById() which fails because
> that script is being executed in a ScriptFrame instead of ContentFrame where
> the iframe resides.
> One solution would be to enable the rpc.js to load in a separate frame by
> introducing a "context" object that can be set. This would be similar to
> what dojo.setContext accomplishes. However, this solution would still
> require some prototyping to see if it's feasible.
