[udig-devel] ShapeType changed illegally from Point to Undefined

[Jesse Eichar]

Hi,

I remember trying to fix a related problem.  It occurred when a new  
shapefile is created then points are added to the file.  Try uDig  
1.1RC5 and see if this problem is fixed.  If it isn't let me know and  
I will make sure I can fix it.


I'm quickly having a look at the code right now to see if there is  
any obvious problem.
