Re: [Zope-dev] Store values thread-wide ?
Look into one of the many session products. There's a proposal about bringing this into the Zope core too. Have a look on dev.zope.org. cheers, Chris Martin Grönemeyer wrote: Hello everyone, I'm playing around with Zope-Objects and find out, that the SecurityManager holds it's informations only for one request. If the Zope-Publishing starts, an existing SecurityManager gets destroyed via __bobo_before__ (am i right ?). In the next step, a SecurityManager-Object is instanciated by the validated_hook in the traverse-method of the BaseRequest. In my own methods i can now get the security-manager and set own properties in this object. I know, this is dirty and i won't use it in real life, but has anyone an other idea how to store informations thread-wide ? Hope you won't kill me. Martin i.A.

Re: [Zope-dev] Debugging ConflictErrors
Hi John, This is one of the problems with SkinScript, and I've not found any great way to sort through it. Here are my two (three?) cents worth 1) Break the SkinScript triggers down to the simplest possible event, and test them individually. If this is not possible, then debug the trigger with a 'pseudo' event that you can generate deliberately. 2) Try Steve A's DummyDataSkin from his add-on utilities. It can be a great help in sorting out what's going on 3) Get down to the debugger. It's not as easy as debugging 'plain' zope since the 'trigger' objects are 'compiled' but you should at least be able to step through a 'commit' and see when they are hitting exceptions etc... -steve "John" == John Eikenberry [EMAIL PROTECTED] writes: John Hey all, John Using ZPatterns, I have a set of specialists/racks/dataskins John that have a dependency relation.

The usual method for this is to subclass from a class you define in Python, then you can change the base classes of that python class easily. For this you need to make a python product with your class in it and initialize the product, registering the class as subclassable. There's probably a how-to on it somewhere, otherwise you can check out lib/python/Products/ZCatalog/__init__.py to see how the ZCatalog class is made ZClass subclassable. -Michel ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
[Zope-dev] calling dtml method with same name up the hierarchy.
I'd like to be able to nest footers and headers.

[Zope-dev] DataSkins containing DataSkins
I have an idea for getting around my ConflictError problem without a major redesign. But it involves DataSkins containing DataSkins. I have a few questions about this... The base DataSkin will be in a Rack. Would there be any issues in making the embedded DataSkins (contained on the base DataSkins) use this Rack as well? Seems like it might result in the confusion about which DataSkin a PlugIn on the Rack worked with. Would it be better to use Customizers in some way... either have the base Dataskin or perhaps the Specialist also inherit from the Customizer? Phillip, I think you've considered this (didn't you once mention converting PropertySheets to DataSkins). What issues do you think I should be aware of in planning for this. I tried to dig around in the list archives, but I couldn't come up with a search pattern with any applicable hits. So I'm sorry if I'm reiterating something already discussed.
