ListGrid addData custom error message

SmartCLient v 91p

Hi,
I have a ListGrid and I need to perform some custom checks in the DMI before adding a new record.
If the checks fails, I need to add an error message in the DSResponse;
on the client side, the addData()'s callback will show the custom error message.

My js call is like :

 listgrig.addData(record, function(dsResponse, data, dsRequest){
 
	if (dsResponse.status < 0) {
	  .... show error message
   }else{
	   ....do something
   }
 },{willHandleError: true});

DMI server side code is like..:

  public Map add(Map record){
	Map x = new Map();
        DSResponse dsResponse = new DSResponse(); 
	
	.... perform custum check...
	
	if (..check OK){
	
		...add record
	
	}else{
		dsResponse.setStatus(DSResponse.STATUS_FAILURE);
    	        dsResponse.addError("myError", "MyErrorMEssage");	
	}
	return x;
  }

My problem is that, although on server side the dsResponse is correctly set with the error Status ( STATUS_FAILURE ) and message:
status = -4
errors = [{myError={errorMessage=MyErrorMEssage}}].

These attributes 'disappear' on the client side. In the callBAck function, dsResponse status is : 0 and no error message is present.

Any clue ?

Thx

See the QuickStart Guide - by calling addError() you have just added a validation error for a specific field. You want to signal a general error.
