Data processort debug

Hi there,
I used dhtmlxDataProcessor for interact with server But there is a problem. User have to refresh page for new request (sendData) whenever request is not successful (for example error in foreign key or …)

What do I do?

Which version of dhtmlx you are using ?

Be sure that even in case of server side error, script must return valid xml data to client side. ( valid xml with action tag and valid sid attribute )

Starting from dhtmlx 4.1 it is not mandatory anymore. Client side must work correctly even after invalid responses from the server side.

It was done by create valid XML
