With BusinessConnect 7.x when navigating through audit log screens (i.e Back, Next, Resend buttons), a blank screen appears, which can only be cleared by refreshing the Administrator screen.

This seems to be caused by a tomcat's enhanced security check which changes tomcat behavior in the Administrator.   This can be corrected by adding the following attributes to the Connector tag in TIBCO_HOME/administrator/domain/<domain>/tomcat/conf/server.xml

relaxedPathChars="[]" relaxedQueryChars="[]"

For example:-

<Connector port="8660" maxHttpHeaderSize="8192" maxThreads="150" minSpareThreads="25" enableLookups="false" acceptCount="100" connectionTimeout="20000" disableUploadTimeout="true" redirectPort="8443" relaxedPathChars="[]" relaxedQueryChars="[]"/>
