Forum OpenACS Q&A: Re: Jeff's Photo Album
Could you check with the api browser if the procs tcl file is sourced in the first place. Go to yoursite.com/api-doc, then click Photo Album 4.5d and you should have the tcl/photo-album-procs.tcl as the only one in the files list. If it's there, click it and you should see about 25 procs (including the one you're missing) in the public procs listing.
If you don't see the file there at all, it hasn't been sourced. If it is, we have to seek the solution from some other sources.
