Hi,

Oracle.DataAccess, Version=4.112.2.30
VS 2010
Windoze XP
IIS and VS Development Server

From within a web application I get the following error:

[System.AccessViolationException] Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

at Oracle.DataAccess.Client.OpsDac.GetType(IntPtr pOpsConCtx, IntPtr pOpsErrCtx, IntPtr pOpsDacCtx, OpoMetValCtx* pOpoMetValCtx, OpoDacValCtx* pOpoDacValCtx, Int32 bSkip)

at NOVDataSets.NOVDSTableAdapters.NOVITEMSTableAdapter.GetData() in C:\ITestWeb\NOVsolution\NOVDataSets\NOVDS.Designer.cs:line 4880

This error is consistantly produced when I NULL a UDT field value from codebehind and reload a grid. Could be a "red herring" for all I know but here it is. The manipulation of any other column values(they are all well known types) does not produce this result. Any thoughts would be appreciated.
