[Zope] Strange ZSQL error in ZMI

[Schmidt, Allen J.]

Jim,

I took the QSurvey.zexp file you sent to me, and imported it into
ControlPanel/Products. No problems there.
but, our site is too big for a full site FIND....times out. 

BUT, whilst poking around, I ran across a copy of the folder where the
original survey was. I deleted that survey and we removed the ZClass again.
Everything works fine now. The Advanced TAB on ZSQL Methods is functioning
again.

THANK YOU!
