I'm having trouble figuring out how to do a "hierarchical frameset" in a perl CGI. The desired result is a set of frames with a parent/child relationship, e.g. department, team, and member. Each of these frames has a form which, when updated, causes that frame and "lower" ones to be updated.

I currently have a non-frame implementation, as well as the beginnings of a frame implementation. The problem is that, while I can get a form submit to update it's source frame, or a single target frame, I can't find a way to update multiple frames. I.e, submitting the department form should cause updates for all three; submitting the team form would cause updates in the team and member frames; and the member form would update only the member frame.

FWIW, the frame version of the CGI currently has a dispatch table with actions for each frame and form.

It seems a nested/recursive solution is called for, but the implementation eludes me. Any pointers or hints ??

• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
