Sample Container RPC Javascript Errors
--------------------------------------
Key: SHINDIG-1380
URL: https://issues.apache.org/jira/browse/SHINDIG-1380
Project: Shindig
Issue Type: Bug
Components: Javascript
Environment: Linux Server
Firefox 3.0 browser with Firebug installed
Shindig SVN revision 962749
Reporter: Randy Watler
Fix For: 2.0.0-RC1, 2.0.0
Attachments: container-osapi-handle-gadget-rpc-method.patch,
gadget-rpc-transport-container-init.patch
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
isapi.container.listMethods).
