this.obj.firstChild is null when loading grid structure from xml I am using a grid in my application. Initially I was creating the grid and structure using the method calls (e.g. setInitWidths, setColAlign, etc) When I switch this to use an XML structure the data does not load and I get the error message this.obj.firstChild is null in dhtmlxgrid.js line 777 if (_isKHTML)this.obj.appendChild(r);else {this.obj.firstChild.appendChild(r)}else {this.rowsCol[ind].parentNode.insertBefore(r, this.rowsCol[ind])};this.rowsCol._dhx_insertAt(ind, r);return r}, I have not loaded any data into this particular grid yet, so I am not sure why this message comes up (I have 5 grids in my app and they were all working before I prior to my switching to xml files) <?xml version="1.0" ?> <rows> <head> <column type="ro" width="50" sort="int" align="center">Row #</column> <column type="ro" width="60" sort="na" align="center">Links</column> <column type="ro" width="100" sort="str" align="center">Document ID</column> <column type="ro" width="75" sort="str" align="center">Collection Name</column> <column type="ro" width="90" sort="str" align="left">Geo Ref</column> <column type="ro" width="75" sort="str" align="center">Load Date</column> <column type="ro" width="80" sort="int" align="center">Confidence</column> <column type="ro" width="80" sort="int" align="center">Country Confidence</column> <column type="ro" width="75" sort="int" align="center">Latitude</column> <column type="ro" width="75" sort="int" align="center">Longitude</column> <column type="ro" width="630" sort="str" align="left">Snippet</column> <beforeInit> <call command="setSkin"> <param>modern</param> </call> <call command="enableMultiselect"> <param>false</param> </call> <call command="setImagePath"> <param>js/grid/imgs/</param> </call> </beforeInit> </head> </rows> Answer posted by Support on Feb 05, 2009 07:43 The same XML works correctly in local samples ( attached ) The error similar to one in your case, can occur if you calling some data manipulation methods without creating grid's structure ( be sure that previously used XML, without head section, not cached ) Attachments (1)
