benjaminberry,

First thanks for your share.

I have a problem with casting Record to ListGridRecord...

I work with SmartGWT 2.2, Java 1.6 and GWT 2.0.4, but also I tested with SmartGWT2.1 and It's the same...

This not compile:
ListGridRecord[] records = response.getData();

And this...,
ListGridRecord[] records = (ListGridRecord[]) response.getData();

...throws java.lang.ClassCastException: [Lcom.smartgwt.client.data.Record; cannot be cast to [Lcom.smartgwt.client.widgets.grid.ListGridRecord;

Can you help me? Thank you so much.

Hi,

Does anyone know how to make gwtrpcdatasource to fetch/update data from a web service which sends json data.

Here is what I assume we should do. If anyone has other ideas then do let me know :

1. In the impl file connect to the webservice using some http connector api.
2. The result is a json string.
3. Parse the json using some json parsing api and copy in the data beans
4. Add these to the list and return.

Isn't this a lot of overhead?
