afterSubmit: function(serverStatus, aPostData) {
                  var jsonText = serverStatus.responseText;
                  var objStatus = eval('(' + jsonText + ')');
                  if (objStatus.status == 'false') {
                    return [false, objStatus.message, ""];
                  } else {
                   return [true, "", ""];
                  }
  }

As I explain in my previous post the afterSubmit function should return

certain values. Just try this

afterSubmit: function(serverStatus, aPostData) {
  var respuesta = serverStatus.responseText;
  return [false,respuesta,""];
}

My javascript code is:

afterSubmit: function(serverStatus, aPostData) {
  var respuesta = serverStatus.responseText;
  alert(respuesta);
}

But the error is shown after the alert().

The error is in grid.formedit-min.js

You should not compare this way

if(ret[0]==false) since this is internal array instead use this

afterSubmit: function(serverStatus, aPostData){

var respuesta = serverStatus.responseText;

var mydata = eval("("+respuesta+")") ;

if (mydata[status] == false) { // or mybe mydata[status] == 'false'

...

return [false,mydata[message],""];

else { return [true,"",""]; }

}

But still got the same error message:

ret is undefined
complete()()grid.for...it-min.js (line 18)
complete()jquery-1....6.min.js (line 29)
handleError()()jquery-1....6.min.js (line 29)
[Break on this error] if(ret[0]==false){$("#FormError>td","#"+...erEdit)$($t).setSelection(postdata.id);}

I think that the error is what I need to pass something in the aPostdata array because I think if the first element in the response it is false, the code needs to show the field with error.

Am I right ? If so, how I pass an array in aPostData ?

sb.append( "[{status:\\"").append(BooleanUtils.toStringTrueFalse(this.isStatus()));
 sb.append("\\", message:\\"").append(this.getMsg().trim());
 sb.append("\\"}]");

 try {
            response.setContentType("text/plain");
            PrintWriter out = response.getWriter();
            out.print(sb.toString());
            out.flush();
            out.close();
        } catch (Exception ex) {
            ex.printStackTrace();
        }

It is the same code that i used to return json data to be shown in the grid...

Could you please post your code. This event in all cases should return

a array instead of result - i.e.

if(some condition) {

return [true,"",""];

} else {

return [false,"Message",""]

}
