Hi, We are evaluating a free version with intention to buy enterprise.
I am using ConnectorServlet but it does not actually update a database (MySQL). DataProcessor debug shows:
 row DBF1VAL1 marked [updated,valid]
 Initiating data sending for DBF1VAL1
 Sending in one-by-one mode, current ID = DBF1VAL1
Parameters sent to server show updated value (c1=XYZ)
 gr_id=DBF1VAL1
 c0=DBF1VAL1
 c1=XYZ1
 c2=null
but table is not updated and server returns a response with an old (unchanged) value:
id=‘DBF1VAL1’><![null]]></
What am I doing wrong?
Is there a way I can see actual update query?
Thank you,
Eugene
Double check that connector.js file is included on the page. It seems that it missed in your case. ( it need to be included after dhtmlxdataprocessor.js )

 gridConn.enable_log(“path to log file”);
