I am getting the same error. I have placed the files as stated in the above URL. But still the error persists.

I tried the resolution given at Forum Index > infragistics.products.netadvantage.jsf.grid > ‘ig is undefined’ javascript error in demo also. However, it is not rendering the table itself if I place the resources in WEBINF.

When I place the resources folder in my webapp, I am getting the Grid (table with title and headers). But I can not see the rows of the table.

When I download NetAdvantage, I can not see igf_effect.js file in lib\runtime\resources\infragistics\scripts folder. Is that could be a problem?
