Subject Re: If tag expression problem
Date Fri, 08 Oct 2010 09:57:15 GMT
I think there is a type mismatch too.

Converting the array [pages] to strings should work,

can you post your code, show us how you convert it?

Or, you can try this:

<s:if test="#it.toString() == #parameters['page']">

see if it works.
