--------------------------------------

Hi [~faizel]! I've pushed a fix for this [1]. Need to add more tests to check all our tools, as I've checked only maven plugin so far.

> During cgen execution, the {{DataChannelMetaData}} instance is not set upon data map load. It looks like {{CgenModule}} does not bind to the {{ExtensionAwareHandlerFactory}}, nor does it load the {{InfoExtension}}, so when the data map is loaded, the metadata instance is null. This causes metadata lookups to fail from the {{MetadataUtils}} class that is supplied to the velocity context during class generation.
> I *think* fix is to have {{CgenModule}} bind to the {{ExtensionAwareHandlerFactory}} and then let {{ProjectModule}} contribute the {{InfoExtension}}.
