problem during deleting a row

Hi,



I am using dhtml DataProcessor, I am trying to delete a row and saving the changes I am getting the following error message:



Error: ‘_childIndexes’ is null or not an object

File: dhtmlxgrid.js

Line: dhtmlXGridObject.prototype={ …

cells:function(row_id, col){…    

var cell = (c._childIndexes ? c.childNodes[c._childIndexes[col]] : c.childNodes[col]);



This was came while

1) first I deleted the row from the grid using following function

function deleteRow(abcd)

{



if(confirm(“Are you sure you want to delete row”+abcd)){

mygrid.deleteSelectedItem();

}

Then the row was Scratched in grid.

2) I am trying to save the changes using SAVE button, I am getting the error.



Grid Initialization Code:



if(typeof(mygrid) == “undefined”){

mygrid = new dhtmlXGridObject(‘gridbox’);

mygrid.setHeader(levelHeader);

mygrid.attachHeader(header);

mygrid.setColumnIds(columnIds); // here the ID’s of columns need to be set



mygrid.setInitWidths(intiWidths);

mygrid.setColTypes(colTypes);

mygrid.setColSorting(colSorting);



mygrid.setImagePath(“images/treeImgs/”);

mygrid.setSkin(“xp”); // moved before setAwaitedRowHeight

mygrid.enableSmartRendering(true);

mygrid.setAwaitedRowHeight(25);



mygrid.setEditable(mygrid.isEditable);



mygrid.init();



//function called when editing of a cell

mygrid.attachEvent(“onEditCell”,function(stage,id,ind,value){

if (stage==2) {

var type = mygrid.fldSort[ind];

var columnId = mygrid.getColumnId(ind);



if (!some_check(value,type,columnId)) {

alert(“incorrect data”);

return false;

}

}

return true;

})

mygrid.attachEvent(“onXLS”,function(){



//show loading message here



document.getElementById(‘message’).style.display=‘block’;



})



mygrid.attachEvent(“onXLE”,function(){



//hide loading message here

document.getElementById(‘message’).style.display=‘none’;

})





mygrid.clearAll();

//before loading set cursor to default

document.body.style.cursor=‘default’;



mygrid.loadXML(‘fetchGridData.do?methodName=loadGrid&prm1=’+param1+’&prm2=’+param2);

//============================================================================================



myDataProcessor = new dataProcessor(‘fetchGridData.do?methodName=loadGrid&prm1=’+param1+’&prm2=’+param2); myDataProcessor.enableDebug(true);

myDataProcessor.enableDataNames(true);



myDataProcessor.setUpdateMode(“off”);//available values: cell (default), row, off

myDataProcessor.defineAction(“error”,myErrorHandler);

myDataProcessor.defineAction(“insert”,setUserDataFunction);

myDataProcessor.defineAction(“delete”,setDleteFunction);

myDataProcessor.defineAction(“update”,setUserDataFunction);

myDataProcessor.setTransactionMode(“POST”,true);

myDataProcessor.init(mygrid);

setGlobalUserData(colNullable);



}







/Thanks

The original reason of the error - the some API call was executed against not existing row.
The issue may be caused by incorrect response from dataprocessor - it may be incorrect @sid or @tid value in response.
It hard to suggest anything without ability to reconstruct the problem  - if it still occurs for you - please provide any kind of demo link , where issue can be reconstructed ( you can send details to support@dhtmlx.com )
