[Dojo-interest] JSONRestStore lazyload

[Cosmo Scrivanich]

Just curious how you are initiating your question.  Are you posting to a
forum topic or sending a email to some dojo help email id?  Only asking

and had no responses.  I thought there might be a better way to ask
questions.

Your tree has "node_name" as the label attribute? Your store needs to
have the "labelAttribute" property set to "node_name". Also, when JRS
does a GET for /31, it expects to get an object in response:
