Good evening everybody! I have some question regarding attribute and agent programming for ZPatterns. I have some provider which is registered for the "handlers" and "attributes" methods and some attributes. My problem is when trying to create a new object and directly editing it, e.g. obj=newItem() obj.propertysheets.data.manage_changeProperties(foobar=13) the propertysheet is defined and my provider is also registered for handling the property "foobar". Unfortunately my SetAttributeFor() method is never called. Also defined in my provider are _objectAdded(), _objectAdding(), _objectChanged() (but not _objectChanging()). Here's what they do: _objectAdded() is storing the data collected via SetAttributeFor() into an sql database as new record _objectAdding() is doing the same as the original method but also committing the transaction as otherwise the new record will not be stored into the database (basically it calls _objectAdded() via the transaction mechanism). I needed to do that as otherwise a getattr on the primary key (==loadAttrib) failed as I try to retrieve the record inside the _AttributeFor() method. _objectChanged() doing the same as objectAdded() but updating the sql database. So what's happening is that _objectAdding() and _objectAdded() get called from the newItem() call but _SetAttributeFor() is not called. When doing the manage_changeProperties() inside a new method which is called manually (and does a getItem()) everything is fine. I've also tried to do obj=newItem() newid=obj.id obj2=getItem(newid) obj2.propertysheets.data.manage_changeProperties(foobar=13) but this also did not call _SetAttributeFor(). So does any ZPatterns wizard has any idea on what I might do wrong? (I can also send someone the source code if this message seems too confusing ;-) regards, Christian Scholz PS: What I am trying to create is an sql attribute provider for ZPatterns which is some replacement for manually creating the zsql method and SkinScript methods. Unfortunately it seems more difficult than I thought at first ;-) -- COM.lounge http://comlounge.net/ communication & design info@comlounge.net
