Hi Sathish,
Yes, this is a known issue with IE9 and below. Orbeon Forms could generate a readonly="readonly" instead of disabled="disabled" on the HTML form fields, but this poses problem of its own and Microsoft fixed this in IE10, so now the incentive to change this is lower. I've put some notes on the issue below:
https://github.com/orbeon/orbeon-forms/issues/1855Maybe we could consider implementing an option to generate `readonly` instead of `disabled` to get around the issue on IE9 and below. But I think we would need to have a customer with enough motivation to sponsor this work for this to happen.
