Re: [udig-devel] BasicFeatureRenderer not happy when shapefile is missi

[Tore Halset <halset@xxxxxxxxxxx>]

Hello.

Sorry for answering this old mail. Did anyone create a jira issue for  
this one?

I used to use the world shape file from diva-gis as a background. It  
used to work with uDig 1.1.x around may 2007, but not now. uDig  
complains about sourceCRS being null.

I can switch to a different background map, but it looks like it is  
pretty common to distribute unprojected shape files without the .prj- 
file.

 - Tore.
