I've set up an error page for my JSPs, and declared it as so(isErrorPage="true"), and configured all my JSP pages (errorPage="/erro.jsp").
It's really weird... I thought the error page should have a clean fresh start, not with any prior output... right???
Trying to debug it I came with something that worked, but it didn't give me a solution nor understanding of the problem... If I put a <%@page buffer="200"%> on the error-generating page, the error page works 100%, with a clean output.
Can someone explain me why this is??
