[CForms] q'n about

[Mark Lundquist <lu...@gmail.com>]

Hi,

I'm working on a time-reporting application with a form that contains 
"day of the week" input fields for Sun-Sat (into which the user enters 
their daily hours).  I'm looking for a way to aggregate those daily 
hours fields within the form model so that I can easily iterate across 
them in the flowscript.

I thought that I might be able to do that using <fd:group>, but I 
realized I don't know how to traverse the resulting form instance in 
the flowscript (where do I find the widgets), and (probably related) I 
don't know how to designate them in the JXT.

Any help?

thx-a-lot,
—ml—

Not sure from your description if fd:group is the best tool for your 
goal, but I'll try to answer your questions.

In flowscript, you can traverse the widget tree with the form instance's 
lookupWidget method:

    form.lookupWidget("groupA/groupB/field");

The argument is an xpath-like syntax.  Your fd:groups are container 
widgets so they'll be nodes in the path.

In your JXTemplate, you use the ft:group element.  See the Template 
section on 
http://cocoon.apache.org/2.1/userdocs/widgets/widget_group.html and let 
us know if you have any more questions.
