[chef] Re: Re: Re: Re: The Application Cookbook Pattern vs. String / Node Attribute Interpolation in Attributes files

Thanks, that works!

I'm using a slightly modified variant now which I find a bit more readable: `node.from_file(run_context.resolve_attribute("java", "default"))`

Found the hint here:

http://docs.opscode.com/chef/essentials_cookbook_recipes.html#reload-attributes

Btw: mind posting the link to the Jira issue?

Cheers, Torben

Now that Jira is back, just add this to the bottom of your attributes file: node.from_file(run_context.resolve_attribute(*parse_attribute_file_spec("java")))

I also tried renaming my application cookbook and attribute files so that they come alphabetically before "java", but that didn't make any difference too (surely because of the `include_recipe "java"`).
