Hi, Alex, great news. I just gave it a first shot and want to take the opportunity to report a problem that I’m having with the b\_prime\_tree. I’m creating testfolders and documents from within root and happen to get something like: mysql\> use hieraki2; Database changed mysql\> select \* from nodes; ±------------±------------±--------±---------±----±----+ | name | parent\_name | page\_id | position | lft | rgt | ±------------±------------±--------±---------±----±----+ | ROOT | 0 | 1 | 1 | 1 | 4 | | JanPrill | | 2 | 1 | 0 | 0 | | Root.child1 | | 3 | 2 | 0 | 0 | | Asdf | | 4 | 3 | 0 | 0 | | MalSchauen | | 5 | 4 | 0 | 0 | ±------------±------------±--------±---------±----±----+ 5 rows in set (0.00 sec) Neither parent\_name nore the lft and rgts of the tree get adjusted. Do you have anything like this experienenced or got any idea why this is happening? Regards Jan ---

Hi Jan, install Hieraki version 2.0.1 and the problem should be solved. It contains a workaround for the bug in rails. regards, Helmut Am 01.01.2006 um 22:47 schrieb Jan P.: > I think so.

Tobi Lütke contacted me and suggested I should pull in the rails patches. So there is now a 2.0.1 release that is much easier to install. ---

After thinking about it a little bit longer I realized that many people would miss the README anyway. So shipping Hieraki 2.0.1 with the rails\_patches included makes most sense. Thanks for the feedback! – [www.hieraki.org](http://www.hieraki.org) ---
