Grouper Users - Open Discussion List

["GW Brown, Information Systems and Computing" <>]

Hi Monica,

Currently, the debug prefs only work if you have an expanded WAR. It may 
also only work on Windows systems. The preferences are saved to file so 
that they can be read in later, saving re-typing paths. Unfortunately, I 
didn't make the file location configurable - something I will do in due 
course.

For the time being you can update LowLevelGrouperCapableAction and 
SaveDebugPrefsAction. Look for a String variable 'prefsFile' and change to 
something that will work on your system.
