[udig-devel] get currently selected features?

[Jesse Eichar]

Hi Vince,

You have to look at the comment before that about the query that is  
used.  There is a comment that discusses what a query is.  In the  
example the second parameter is new String[0], which indicates that  
no attributes will be loaded.  You can remove that parameter and all  
attributes will be loaded (this will be slower of course).  Or you  
can do an array of the names of all the attributes you want to load.
