I have some problems with unhandled exceptions witch is crashing our application.

It seem to happen, when Oracle is disappearing, i.e. database crash or loss of connectivity, not every time - but once in a while.

I have grapped this from the application window:

Unhandled exception: System.NullReferenceException: Object reference not set to an instance of an object.
at Devart.Data.Linq.Engine.dv.a.a(bn A_0)
at Devart.Data.Linq.Engine.dv.a(bn A_0)
at Devart.Data.Linq.Engine.dv.a(Int32 A_0)
at Devart.Data.Linq.Engine.dv.a(c A_0)
at Devart.Data.Linq.Engine.dv.c.b()

I am using dotConnect for Oracle version 8.2.100.0. The database is a version 11.2.

Please advice.

There were a lot of fixes regarding this error since dotConnect for Oracle 8.2.100.
Please try upgrading your dotConnect for Oracle to the latest one. The latest build can be downloaded from http://www.devart.com/dotconnect/oracle/download.html (trial version) or from Registered Users' Area (for users with active subscription only).

Please tell us if this helps.
