Is this a user control you created?
Please give me the specifics of what you are trying to do and how. The error
indicates an problem in the parent-child relationship in the control
hierarchy.

Do you modify the page at all? Sometimes modifying the
page causes the error you described. Alternatively, you
do not have to use ViewState in your page.

Both server and clients are running Framework 1.1.
We are in a single-server environment.
We have tried the TemplateSourceDirectory fix, the machineCode fix, and the EnableViewStateMac="false" fix.
We have restarted our server and our clients.

I have the view below and if I use vwRouteReference as the rowsource

Everything I've read on the web suggests that including the TOP

why the sorting is not working correctly for this particular view? thanks.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
