I have tried to trace this problem thru in code, but never seem to be able to reproduce it while tracing. However, I have pinned it down to a specific set of steps to reproduce it.

1) Add a field to the field repository
2) Add that field from the repository to a table
3) Save.

The debugger shows up. I open the table again in 0 and rerun the offending code and resume. Everything is OK. Any ideas on how to isolate this? I have tried reinstalling SDT on this and other machines and encounter the same error.
