NullReferenceException in DEM Reconditioning with 10.1

Discussion created by arimandrona on May 7, 2014
Hello, I'm having problems with the DEM Reconditioning feauture of ArcHydro 10.1.

The error is:

System.NullReferenceException in ESRI:APWR.ApHYdro.ArcHydroOp.DEMReconditioningGP in C:\Builds\HydroSolutions\10.1_ArcHydro\Sources\ArcHydroTools\src\ApHydro\ArcHydroOp.vb:line 60426

The same function with the same input data works in the same computer if the 9.3 release is used instead of the 10.1, so I think the problem is not with the data unless something changed from 9.3 to 10.1.
I have checked the recommended solutions for ArcHydro Problem Solvers, and none seems to help. I've also seen recent threads about DEM Reconditioning issues but the error I got seems to be different.
Any idea or hint is greatly appreciated.
