JsonRestStore problem with HtmlUnit resynchronize and PUTs

[ashleymoran]

This was found with Celerity 0.7.5 (which uses a recent HtmlUnit? 2.7 snapshot). I'm not sure if this is a HtmlUnit? bug or a Dojo bug.

Using a Dojo 1.3.2 Grid,

:resynchronize => true causes the an 'edit complete' event to fire and attempts to send a PUT request with an empty body, but an exception is thrown before it leaves Celerity :resynchronize => false apparently prevents the PUT from ever being attempted

It seems like browser resynchronising is affecting the way JsonRestStore? gets run.

My client on this project found a fix:

_overriddenXhr = dojo.xhr;
dojo.xhr = function(method,args,hasBody){
    if (method === "PUT"){
        method = "POST";
        args.headers['X-HTTP-Method-Override'] = 'PUT';
    }
    return _overriddenXhr.apply(dojo, arguments);
}

this changes the PUT to a POST and adds a suitable header such that Merb routes it all appropriately.

(To run the merb app, you need to do merb -I json_server.rb)

I've submitted this to the HtmlUnit? tracker as ​ticket 2898512, as I don't know whether it's a Dojo or HtmlUnit? issue. Sorry for the cross-posting.

If the problem is that Celerity is unable to send PUT requests, that would be an issue with Celerity.
