It seems it can be a problem linked to addRowData method.
Example:
var myfirstrow = {invid:”1″, invdate:”2007-10-01″, note:”note”, amount:”200.00″, tax:”10.00″, total:”210.00″};
jQuery(“#myDiv”).addRowData(“not_numericID“, myfirstrow);
I think it's what is happening (internally) if addRowData's first parameter (id) is not a numeric one there's a conflict and you cannot have a checked checkox on select row.
But how to fix it?
Because in my case i don't call explicitaly addRowData , i only give a recordSet to Jqgrid.
