Re: [Zope] BTree Folders questions
I am using CMF 1.5.2 and Zope 2.8.0 - will upgrading again this week to 1.5.3 and 2.8.1 I removed my BTreeFolder2 product as it was indicating it was duplicated product in my event log after my recent upgrade - so it appears to have become part of the distribution. It is part of 2.8, yes, so you will not need to install BTreeFolder2 separately in that case (you did not mention version numbers in your original mailing). I did not really understand the difference between a BTreeFolder2 and a CMFBTreeFolder since CMFBTreeFolder did not appear as content even though it is displayed as an option in Core Content in ZMI. Content type registration for the ZMI and for CMF are two different things. An item showing up in the ZMI does not mean it exists in the types tool. A CMFBTreeFolder is just a BTreeFolder2 with all the necessary trimmings so it plays nice with CMF. Portal buildout upon instantiation and types creation is handled through CMFSetup XML-based profiles. There is no way to express If product A is installed, install type B. So for CMF 1.5, which can be run on Zope 2.7 and 2.8, you will have to do this step manually, tough luck, nothing you can do about it. In CMF-HEAD, which depends on Zope 2.8 and thus guarantees the availability of BTreeFolder2, it is an oversight that CMFBTreeFolder is not one of the automatically installed types upon portal instantiation. I filed a collector issue and will look at it over the next couple days: http://www.zope.org/Collectors/CMF/371 jens ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

This is really super, Jens! This is what I was hoping. Many thanks for your help and suggestions.

[Zope] BTree Folders questions
How many objects should one have in a single folder to consider using BTree Folder over the regular Folder? Does it make sense to use a BTree folder for 100 - 500 objects or should it be reserved for situations where there are say 1000 + objects or more. Are there any benefits to be gained at the lower end as well or are there drawbacks? On another note, why do CMFBTree folders not appear in CMF? Is this the way they are supposed to work? If so, what differentiates them from a BTreeFolder2 if they are not a type visible to CMF? Many thanks.

Re: [Zope] BTree Folders questions
Hi Jens. Thank you for your advice. I am planning on contents of folders to be no more than 2000 items maximum and using CMFBTreeFolders for larger folders consistent with your recommendations. I am using CMF 1.5.2 and Zope 2.8.0 - will upgrading again this week to 1.5.3 and 2.8.1 I removed my BTreeFolder2 product as it was indicating it was duplicated product in my event log after my recent upgrade - so it appears to have become part of the distribution. I did not really understand the difference between a BTreeFolder2 and a CMFBTreeFolder since CMFBTreeFolder did not appear as content even though it is displayed as an option in Core Content in ZMI. So my content was appearing on the web but not visible in the portal as a folder. I guess I am wondering why isn't it ready to go by default as a core type in CMFDefault. It appears everything is there except registering in types tool. My opinion is it would be really great if it were included as a core type (in the sense it is ready to go as the other types are). It could also remove confusion in ZMI that Core Content will produce content that is immediately recognized by the portal. Many thanks.
