Re: [udig-devel] Dumping Style into file
|
I beleive that if you install udig (a normal version) you can download a
extension using the update manager (under help) that exports the style of a
layer to a file. The code can be found in the repository under community/jesse
I believe.
As for what you are doing wrong and how we should be doing it right.... I'm not
100% sure to be perfectly honest with you. What happens if you do a getString
on the momento? does it change the < and > back?
