Hello, I am developing an External Method that checks for several parameters to be passed and does a lot of insert/updates in an Oracle database... I have several "checkpoints" and when one fails I want to be able to do a raise and rollback all the open (uncommited) transactions, since the DCOracle is a Level 3 adapter, there is no problem, because the transaction mechanism from Zope is integrated. But know here comes my question: how do I rollback a transaction without doing a raise? I need to do this to server diferent error pages when an error ocurrs... I mean, I have to present for example a form with all the fields the user filled in, or if there was another error, present another form. I do not want to use the standard_html_error ...
