S2: Problem Infinite recursion detected

Hi, We have an action which causes an Infinite recursion detection. I don't have any idea why this is happening. When we call the action the first time everything is ok. But when we call this the second time we get this exception: 05.01.2010 13:45:00 org.apache.catalina.core.StandardWrapperValve
