6. Sample code if applicable:

In ISC_Grids.js line 32407, this.getFields().length is undefined in if statement, causing the grid to fail.

We made a local hot fix by adding a check for its existence before grabbing the length of that object.

. Isomophic please do research on why this.getFileds() returned undefined in IE8.

hideField : function (fields, suppressRelayout) {
arguments.__this = this;

var noFields = true,
allHidden = true;

if (!isc.isAn.Array(fields)) {
fields = [fields];
}
// we shuffle some stored colNums around on edit items - store out the index of each field
// being hidden in an array to make this easier.
var hiddenFieldNums = [];

if (this.getFields() && fields.length == this.getFields().length) {
// can't hide the last bunch of fields
this.logWarn("Attempt to hide all fields in one call - disallowed.");
return;
}
