Print View Not Displaying in Dashboards

If you cannot display the Print view for a dashboard, there might be an issue with the size of the input control values. Input control values are passed as URL parameters on this page, and the application server can limit the length of the URL that includes the parameters.

To avoid this limit and allow large numbers of input control values in dashboard print view, edit the following configuration file, or the equivalent in your application server.

Configure Apache Tomcat to Accept Large Filter Values

Configuration File

<tomcat>/conf/server.xml

Property

Description

<Connector port="8080" protocol="HTTP/1.1" 
           connectionTimeout="20000" 
           redirectPort="8443" 
           URIEncoding="UTF-8"
           maxPostSize="0"
           maxHttpHeaderSize=65535 />

Add the maxHttpHeaderSize parameter to set the number of bytes accepted in the URL by the app server; "65535" is equivalent to 64 KB. For more information, see the Tomcat documentation.
