FYI Grails 1.2 has a fixed JSON builder based on this work!

Hi Marc,

Thanks for this: spent many frustrated hours trying all sorts of stuff with the default Builder before I came across your post…

Thanks again

Surely the correct usage is new BetterJSONBuilder.build { }
When I try your suggested usage new BetterJSONBuilder { }

I get an error saying that no constructor that takes a closure parameter exists.

Thanks for providing this. Its much better than the default Grails JSONBuilder. For others looking at the code, note that there is a typo around line 55 (“} else if (ars.size() == 1) {“) where ‘ars’ should be ‘args’.

Marc — What’s the license for this class if I want to use it in my own grails project?

According to http://www.grails.org/doc/1.1.x/api/grails/converters/deep/JSON.html the deep converter is deprecated. The Converters framework has been refactored and this made the deep Converters obsolete

I was having the same problem as you using the deep converter, it always throws the Value out of sequence JSONException regardless if the data has nested objects or not.

Funny you mention it. I’m about to start a grails-json-plugin for JSON producing/consuming based on Json-lib, which among other things provides its own builder http://json-lib.sourceforge.net/apidocs/net/sf/json/groovy/JsonGroovyBuilder.html
