View Full Version : DirectProxy sending no data on update. Looking at 'jsonData'?

18 Apr 2011, 4:47 PM

I'm trying to get an EditorGridPanel working with the DirectProxy to load, create and update records in a fairly simple grid. It's using metadata loaded from the server response to build the column model after the store is loaded and a few other tricks here and there, but I've got it all working up until saving changes.

Now, it's not using restful services, but I have got the api configuration working properly - which I've confirmed by stepping through the js in Chrome. However, I found that when the record is being saved, the doRequest() function of DirectProxy is looking for data in 'jsonData', when my data is in a property named 'rows'. As per the server-supplied/JSONReader metadata.

I've had a look around the forums and a quick Google and not come up with much as yet, apart from a few solutions involving overriding functions.

It seems someone else has found this problem in version 3.1.1 (http://www.sencha.com/forum/showthread.php?94648-SOLVED-3.1.1-restful-paging-directStore-no-data-in-POST&highlight=editorgridpanel+directstore+update+data), but solved it by modifying their code to work with ExtJS.

However, I'm a bit confused.. Is this a bug?

I found another post referencing version 3.0 RC1.1 (http://www.sencha.com/forum/showthread.php?69415-3.0-RC1.1-DirectStore.api.save-request-params-Question&highlight=editorgridpanel+directstore+update+data) which has different code to that found in my copy of the 3.3.1 release. And after downloading a fresh copy, I found the same code.

I kept looking, but nobody has any explanation why this was changed back to point directly at 'jsonData'. So am I doing something severely wrong? Or is this indeed a bug?

Sorry for the overly verbose post, but I wanted to be clear. This is fairly important to my project also.

Thanks in advance for any feedback!


And so setting encode to false on the JsonWriter managed to make it work? How does that work?!
