Subject Re: c:forEach issue in JSF 2
Date Wed, 01 Jul 2015 08:01:05 GMT
Hi Thomas,

Thank you for the quick reply!

I am using JSF 2.2. As mentioned in my previous email, I have huge code
base which is using c:forEach tag. So, it would be really great if I can
figure out the real issue with c:forEach.

If there is not other way to make c:forEach work, I will have to switch to
ui:repeat.

Thanks!
