Hello,

I got an exception stack trace from a production app, the start of which looks like this:

---
java.lang.IllegalStateException: _beginTransaction(): com.webobjects.eoaccess.EODatabaseContext com.webobjects.eoaccess.EODatabaseContext@1162212 Transactions cannot be nested

ERXApplication.extraInformationForExceptionInContext() tells me that it occurred in a component that basically just lists some EOs.  User feedback is a dead end, so I wouldn't even know where to start to reproduce this.  I know I'm not giving much to go on here, but can anyone give me any background on how such an exception might be thrown at that point?

(I'm using WO 5.4.3, and a fairly recent Wonder.)
