RFR[9] S: 8154579: Pagination demo:thrown java.lang.IllegalArgumentException on console, when clicking the link of "VIEW SOURCE"

[Morris Meyer]

Kevin and Jonathan,

Please review these changes to Ensemble8.  The View Source feature 
parses the source for Strings that look like urls, and was getting 
thrown on using String.format to build a url programmatically.

Thanks,
