Hi, I've a requirement where my application needs to just browse the folder listing using collapsible/expandable trees. dtml-tree is just perfect for this. My application has a DTML document called /myapplication/browse_files.htm I pass a variable to this called BASEURL and that is the root URL from where I want the hierarchy to be displayed. Code is like this: Assume BASEURL has a value http://localhost:8080/mysite1/subsite2/ <dtml-try> <dtml-with "REQUEST.resolve_url(BASEURL)"> <dtml-call "REQUEST.set('currFolderId',id)"> <dtml-tree currFolderId branches_expr="objectValues(['Folder', 'DTML Document','Image','File'])" nowrap=1 sort=id> <IMG SRC="<dtml-var SCRIPT_NAME>/<dtml-var icon>"> <A HREF="<dtml-var absolute_url>"><dtml-var title_or_id></a> </dtml-tree> </dtml-with> <dtml-except> Error here </dtml-try> Now it all works fine initially. When the + sign is clicked to expand a folder, the BASEURL is not passed forward to the resulting display. That causes an error. I'm now passing BASEURL as a session variable, which I think is an ugly solution. My question is: 1. Is there any way I can pass BASEURL to the URLs generated when tree is browsed? 2. Or is there anyway this BASEURL thing can be avoided in the drill-down pages? If it helps, my application is something which will allow users to browse the folder structure and choose a document to make a hyper link from their document. Any pointers, solutions etc will be greatly appreciated. TIA http://vsbabu.csoft.net "The man who smiles when things go wrong has thought of someone to blame it on." --- Jone's Law
