[Erp5-dev] problem with before r18480 site update!

[Mikolaj Antoszkiewicz]

Hello,

At revision 18480 Base_updateListboxSelection script was introduced.
At revision 18525 it is used in Base_doDialog action.

When upgrading site from revision <18480 to revision >18525 it's 
impossible to upgrade Business Templates since one gets AttributeError 
trying do to anything in Import/Export dialog, since there's no 
Base_updateListboxSelection yet.

I guess Base_doDialog would need to take that kind of situation under 
consideration somehow. Or maybe not....

Well, anyway I found such a 'corner' case and dutyfully am reporting. :)

P.S. Other approach would be to upgrade in two phases - past 18480 and 
then past 18525. For new sites there is no problem with that of course.
