[Gvsig_english] Problems with EPSG.21781

[Francisco José Peñarrubia]

Hi Lorenz.

I think this is a different problem. The gvSIG driver is not 
reprojecting, so, I think the problem is not related with the kind of 
projection.
I guess there is a problem with an Integer field in your table. Try to 
select only the geometry field for your layer in order to isolate the 
problem.

To be sure about this problem, we need to connect to your data. Is it 
possible to do so? If yes, you can use my private mail, don't send the 
parameters to the whole list.

Cheers.

> Therefor I would like to check the hack from Frank. But as I'm new in that proj-stuff I have no idea where to find the PROJ.4 epsg init file. And is just enough to change the <21781> entry in that file and afterwards to restart the program? Thanks for helping a greenhorn.
