> Several Javascript errors are present in the browser while starting the Sample Container
and custom containers derived from it.
> - No relay set (used as window.postMessage targetOrigin), cannot send cross-domain message
> - Unknown RPC service: osapi._handleGadgetRpcMethod http://localhost:8080/gadgets/js/core:rpc:pubsub:shindig-container.js?c=1&debug=1
(line 779)
> Both of these errors are related to the initialization and configuration of the RPC libraries.
I have attached two patch files that correct these issues.
> The first patch, (gadget-rpc-transport-container-init.patch), disables initialization
of jsonrpctransport.js and gadgetsrpctransport.js in the container context. The code in these
scripts used to assume that gadgets.config variable would only appear in gadgets and not the
container. This changed late in 2009 and is no longer the case. This patch adds some gadgets.config
flags via feature scripts that can be used reliably to determine whether in a gadget or container
context. These flags are then used to enable/disable RPC initialization.
> The second patch, (container-osapi-handle-gadget-rpc-method.patch), again includes the
osapi.js portion of the shindig.container that implements the missing osapi._handleGadgetRpcMethod
handler in feature.xml. It also cleans up some other related issues with the use of container.listMethods
dynamic configuration, (i.e. it no longer attempts to rebind osapi.newBatch or osapi.container.listMethods).
