newTransaction not called in transaction.get
by Jürgen kartnaller 22 Sep '08

22 Sep '08

I just run into a with transaction manager and synchronizers. If transaction.get implicitily creates a new transaction the synchronizers are not called. This is not problem as long as no savepoints are used. If savepoints are used the DataManagers created by synchronizers are not present. Because savepoints are requested from the DataManagers it doesn't work. I already created a branch with a fix (transaction/branches/synchfix). If one with more knowledge about the transaction manager can approve my change I will add tests and merge the change into trunk. Regards Jürgen

Yes, that's fine, "z3c.iban", then. Best Regards, Hermann -- hermann(a)qwer.tk GPG key ID: 299893C7 (on keyservers) FP: 0124 2584 8809 EF2A DBF9 4902 64B4 D16B 2998 93C7

Where to put custom schemas for z3c.form that depend on specific libraries?
by Hermann Himmelbauer 20 Sep '08

20 Sep '08

Hi, I need to create a specific schema for international bank account numbers (IBAN). I'd like to contribute this widget (maybe someone has use for it). However, this schema needs a specific library for validation, therefore I wonder where to put it? If I put it in z3c.schema (e.g. z3c.schema.iban / z3c.schema.payment), the library dependency will be problematic, I assume. Maybe I should create an own package for it? But with what name? What do you think? Best Regards, Hermann -- hermann(a)qwer.tk GPG key ID: 299893C7 (on keyservers) FP: 0124 2584 8809 EF2A DBF9 4902 64B4 D16B 2998 93C7

Hi there, Could we add dates to the KGS releases on the KGS page? http://download.zope.org/zope3.4/intro.html Where are the KGS versions listings tagged in SVN again? A link on the KGS page would be good too. Regards, Martijn

Correction, this is my misunderstanding of sqlalchemy, as explained on irc: <stepz> elro: that's when you do session.begin(autoflush=False) So I should just make it an unconditional flush() Laurence
