WTableView::closeEditors() cause "no active transaction" error when run under transaction

Description

This code works:

view_->closeEditors();
dbo::Transaction t(session());
session().flush();
t.commit();

while this fails:

dbo::Transaction t(session());
view_->closeEditors();
session().flush();
t.commit();

Maybe it is related not with WTableView but with session().flush().

Hey,

Can you provide some more information on steps to reproduce?
I assume your table is linked to a Dbo::QueryModel ?

Also, it would be great if you can run under the debugger to see indeed whether the error is thrown from flush() or from somewhere in closeEditors().

The bug is intriguing since it sounds like a fundamental problem with nested transaction blocks.

Hello!

Yes, the table is linked to a QueryModel.
The error is thrown from flush()

Hey,

I would appreciate a test case that reproduces this. I can't imagine a reason of why this goes wrong.
