Anyone using grailsflow in its Plug-in or Demo version?

Question

Grailsflow seems to be broken (as of Jan 2010) with Grails 1.2 or above, in both 'demo' and the plug-in flavours. Is there anyone out there using it? Have moved code out of the plug-in into my BootStrap.groovy, so the app will start.

@see jcatalog forum post

But still need to work around or resolve the error in all views. See stack trace below:

The error is because it is unable to load the resource bundles for the messages. I moved them out into the default messages.properties file and modified the GSP's accordingly. Now the application starts fine and I can access the pages fine but there are still some errors as below..

Has anyone been able to setup the demo fine?
