Hello,
There is a fix regarding addRowdata and rownumbers in the GitHub,
but you have a not needed comma here:
colModel: [
{name:'parentKeyID', index:'parentKeyID', width:0, align:'center',hidden:true},
{name:'id', index:'id', width:30, align:'center',hidden:true},
{label:'Text', name:'text', index:'text', width:350, align:'center'}, <==== Error
],
Best Regards
Tony
