You must know all of the possible facet types in advance. You don't have to know how many of each type you will have (that part can be dynamic) but you do need to know the finite list of possible facets (foo-folder, etc.)
If you don't want to customize based on the node type you could just make all of your nodes report the same "generic" type and just implement a single facet. Currently there is no automatic default facet if it can't find one. IMO you've got maximum flexability here. You can customize the look of the node based on the type or just give the same look to all nodes. sean On 6/6/05, CHAUDHURI, Neil <[EMAIL PROTECTED]> wrote: > One point I forgot to mention......in Sean's sample JSP where he renders > Tree2, he has a <f:facet> tag for each type parameter in the tree (e.g. > person, foo-folder, etc).
