I have a scenario that is broken and need some help. My situation is this :

1. All IG controls are initialized in the $(document).ready(function()
2. HTML 'select' controls (which are linked to igCombo) have an 'onchange' function attached.
3. This onchange function sets the 'readOnly' option of other IG controls based on its value.
4. As the page loads, the onchange event is triggered BEFORE the document.ready function executes. I don't know why, but it does.
5. This causes a "cannot call methods on igNumericEditor prior to initialization; attempted to call method 'option'" because the IG controls haven't been initialized yet.

How do I fix this? I have a few thoughts :

1. Catch the exception and ignore it
2. Set a global variable called INITIALIZED that onchange checks before it does any of these IG method calls
3. Check if the control is an IG control (meaning its been initialized) before attempting these IG method calls

None of these are very elegant, but #3 would be the most robust solution. Is there another approach I should be using? If not, how do I perform the check in #3 above?

Thank you
