Hello everyone,
i tried to use "BETA2007.gsb" ("Bundeseinheitliche Transformation für
ATKIS" -- Germany) with GeoServer-2.2-beta1. The NTv2-Gridfile is used
for transformations between DHDN and ETRS89.

Results:
Documented example

? failed (NTv2 not used)
EPSG:31468 (DHFN GK4) ? EPSG:32632 (*WGS84*/UTM32)

? ok (NTv2 used)
Another issue:
After adding "BETA2007.gsb" - Im not able to publish a layer based on
EPSG:31468 via PostGIS (connection timeout in the webinterface).
There is a lot of continuing warnings (> 30min):
10 Apr 19:16:51 WARN [geotools.referencing] - Point (4635354.51089324,
5523072.327714653) is not covered by 'Headers : 11

To Min Ax: 6356752.314' NTv2 grid, it will not be shifted.
The example-dataset (administrative units) is usually published in a
second (without NTV2).
