Subject reply: about s:generator (struts 2.1.8) - new information
Date Sat, 17 Oct 2009 03:40:07 GMT
Actually, it's not my company code, just my tester.
I want to test if the "myAtt" in pageContext.
When I use pageContext, I got null from pageContext.getAttribute("myAttr");
When I tried request, I got the thing I want.
I just want to know the reason.

Personally, I don't allow scriplets in our company code, but the value is
placed in the page context, but you're trying to get it from the request
scope.

Try pageContext.getAttribute("myAtt").
