I got the error message:
org.apache.tomcat.util.http.Parameters processParameters
WARNUNG: Parameters: Invalid chunk ignored.

A SDT in ModalPanel, every row with a checkbox, sothat you can select rows and put them to rich:orderingList. By click the checkbox i got the above error message. But the Waring is harmless, the tomcat can continuous to parser the request. But i want to konw, what is the reasons. Thanks in advance.
