Hi there, I'm using perforce plugin 1.1.7. The fisheye diff doesn't work because it uses file revision numbers when it needs to use the changelist revision number. If you leave the r1 value blank then fisheye is smart enough to use the previous revision. For example, here is a fisheye diff that works: https://fisheye.netbase.com/browse/Hudson/depot/branch/maven/src/main/java/Foo.java?r1=&r2=49074
