ZPatterns "0.4.3final" contains a serious bug which deletes all ZODB-stored
contents of a Rack when you use the manage_pack method. This bug only
affects you if you store Rack-mounted objects or attributes in the ZODB,
and does not affect you if your objects are entirely contained in an RDBMS
or
FYI, I have uploaded a release version of ZPatterns 0.4.3 to:
http://www.zope.org/Members/pje/ZPatterns
I have also updated the standalone PlugIns package at:
http://www.zope.org/Members/pje/PlugIns
These are primarily maintenance releases for GUI and security compatibility
with Zope 2.3.x.

Hi Everybody
We are porting a desktop application to Zope using Interbase and ZPatterns.
In this application objects like Vintage, Farm, Vineyard, Block and Panel
form a hierarchy and are displayed with the Zope tree widget. To build the
hierarchy we use a method called getChildrenFor() on each

Actually I was mistaken and SetAttributeFor() is called. Just _objectChanged()

Also commit() is not called at all in this case. It get's called once when the

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=new
With some help from the kind folks on #zope, this has been
solved.

Steve,
This release breaks access to the management screens of ZClasses
stored on Racks.
In Zpatterns-0.4.2a3, Specialist/item_id/manage returns the ZClass
management screen. In your release it returns the Specialist Methods
screen.

I'm providing this for convenience, so that folks don't have to patch
stuff to use ZPatterns with Zope 2.3. Bear in mind that this is not an

Hi,
Is there any way to get ZPatterns working even if you don't have a C++
compiler on Win32?
Isn't there a working dll version available, somewhere?
Thanks, Tom.

I've put an extensive patch to ZPatterns 0-4-3b2 here:
http://www.cat-box.net/steve/ZPatterns.patch
The patch includes the following:
* Fix to _memento class so it works with Zope 2.3
* Alteration to GAPMixin so the the attributes it says it provides come
from the union of the assignments
In a SkinScript COMPUTE statement, should I be allowed to supply
different names in the OTHERWISE LET section as in the attributes section?
For example:
WITH some_query() COMPUTE
foo,bar,baz
OTHERWISE LET
foo='There is no foo',
spoon='There is no spoon'
Looking at the ZPatterns code,
I've written a class called RemoteRack. It works just like a ZPatterns
Rack, except that the BTree it uses internally for storing its
persistent data can be anywhere else in the ZODB.
I'm using it in a FileStorage-based application where I want to have the
application's persistent data stored

Here's my understanding of how Persistent Attribute Providers work:
Persistent Internal Attribute Provider
DataSkins and Attributes are ultimately stored like this:
Rack's BTree

Thanks, Steve, that's great. I can even simplify it since there's
a one to one correspondence between products and images, so I can
just use the product Id as the Image Id. If that correspondence eve
