Hi, I am getting ready to try to tackle this. I want to set up a tree structure that will batch the contents of each branch. i did searches on zope.org, google.com and got individual pointers to either tree or batch but not for both. since it seems a particularly valuable feature (when a branch can contain hundreds of items), i thought it might have been tackled by someone already. so, if anyone knows where the appropriate documentation, how-to, helpful note might be, please let me know. if this has not been done yet, is it something that will require revising the source code? is it impossible, e.g., due to an inherent incompatibility for tree and batch to coexist? Thanks. ciao! greg. Gregory Haley DBA/Web Programmer Venaca, LLC.
