On 1/18, Amos wrote that the use of __bobo_traverse__ isn't necessary, and that "SQL Methods can be treated like containers .. In general you can reference database objects via URLs". Unfortunately, there was no more information than that. What I need to do looks like I'll need to override __bobo_traverse__ in a subclassed folder. have no idea how to do that exactly.. I have a folder hierarchy, like this: /Airports/PTD Where 'PTD' is a subfolder of Airports. If a person enters /Airports/ALB, and ALB does not exist as a subfolder of /Airports, what I want to happen is /Airports/AirportInfo?identifier=ALB So, /Airports/ALB could be either a true folder object under /Airports, and if it isn't there then the equivilant of /Airports/AirportInfo?identifier=ALB should be used instead. It'd be neat if a folder could have a "default document", that is, a document to be loaded if a requested folder object couldn't be found. My default document could then "import" the AirportInfo page appropriatly. Any suggestions? -- Also, regarding using #tree as a within-document expander/contracter, I've been thinking that what would probably be better is something called <!--#toggle--> that works like an <!--#if-->, since that's more in line to what I need. The toggle would be "true" or "false" depending on the cookies, and the default state of the toggle (default false) I've looked at the TreeDisplay source .. hmm. Time to learn python.. What a strange langauge..
