I get this error:
Exception during request processing:
Caused by javax.servlet.ServletException with message:
"Parameter count exceeded allowed maximum: 512"
The number of parameters was limited in all web servers to plug the hashmap collision denial of service attack.
You can raise the limit by adding the following system property to the configuration file (e.g.
<property name="org.apache.tomcat.util.http.Parameters.MAX_COUNT" value="10000"/>
