grid.addRow() issue


I have a dhtmlxgrid. I have a button which allows add row to this grid and also a button which allows delete rows from the grid.

Most of the time add row works fine but sometimes it gives following error in FireFox3 console -

this.cell.parentNode is null

getTitle()(" “, undefined)dhtmlxgridcell.js (line 40)

setAttribute()(” “)dhtmlxgridcell.js (line 39)

getValue()()dhtmlxgr…d_math.js (line 8)

setHTML()(click clientX=378, clientY=56, Object id=Insert className=defaultButton)dhtmlxprotobar.js (line 11)

[Break on this error] this.cell.parentNode.idd,

following is the code -

var rowCount = grid.getRowsNum();


I get the error on addRow. This errors shows up sometimes not consistently.

Can you please help me. Thanks.

the way how you generate IDs are not safe, if rows added|deleted non unique ID can be generated
You can try to use next code instead

var id = grid.uid();
