This might be a bug in the JSP code in 4.1.3 (which is under active development, so might be a little more prone to bugs at the moment). Could you try this under 4.1.6 and see if it works better for you?
There are also some cases in the Struts tags where we've got bugs that only get exposed when tag instances are reused by the container (which was a recently added feature in Tomcat). We're going through the tags on the 1.1 branch before the next beta release to clean this up -- in the mean time, Tomcat offers a configuration flag (in conf/web.xml) to turn off tag instance reuse if this particular problem is biting you.
