Re: [udig-devel] Spaces In FileNames

Hi Emily; I am madly trying to hook up the ID class since I am sick of
all these path based issues in our code base.

So why is the ID class being created with null?

I agree; now I wonder why the provided url is null?

That would probably be correct; since " " is not valid in a URL; can
we detect where in the code this is happening?

Richard made a URLUtils class that handles these cases (I added a test
case based on a File with spaces; but not for a URL with spaces). All
our code should be using this URLUtils; so it is my hope we can use
the debugger to find a case where this is not being called. Use of
this class is covered in the udig coding conventions:
