Hi, Does the wrapper.setDataSourceUrl() method change the reqId value when it makes requests to your server? If so, you'll need to change that value in the text file before sending it back. I'm not aware of any other way to work with a text file as a data source (I didn't see a way in the API to force the value for the reqId).
I don't use wrapper.setDataSourceUrl(), but I do use the query.send() method. With that method, the reqId isn't always 0. If you have multiple requests per page, each request will get a different reqId. And sometimes, even with a single request, the reqId isn't 0.If the reqId received doesn't match what was sent, the query.send() method ignores the response in a manner consistent with what you described. The same could be happening with the setDataSourceUrl method. This can be easy to figure out. You could see what the web browser is sending on the client side, perhaps with firebug or similar, or you could log the exact text of each request on the server side, just by dumping the request to a text file or by inspecting server log files.
