Actions have to be separated by dots, and screens by commas if they're in
subdirectories.
I suggested that we change it so that screens can be separated by dots too,
since that makes more sense to java programmers already, and so it would be
the same for screens and actions. Also, dots appear normally in the URL,
while the browser replaces commas with %2c. People liked the suggestion,
but I never implemented the change. I still plan to change that, along with
the way that actionevents cannot have capitalization in the do methods
except for the third character (ie: doSomething works, but doSomeThing does
not).
The reason you can't use / is because the ParameterParser uses the / as a
name value pair separator character, for other reasons that have been
explained here many times....look at the javadoc for ParameterParser.
