Repeating Sections

I have an issue with a data entry page where I don't know how many items the user will want to list. Think of a request form where the fields for one request start out showing. However, the user can click an add button to repeat that section of fields to add a second, third or fourth request. Is there a way to do this in Orbeon?

The XML would of course be a repeating section like this:
<requestList>
    <request>
        <priority></priority>
        <dateNeeded></dateNeeded>
        <description></description>
    </request>
    <request>
        <priority></priority>
        <dateNeeded></dateNeeded>
        <description></description>
    </request>
</requestList>

Thanks,
Dustin

yes, i use such a construction quite often - you just need to use
xforms:repeat. You could create a html table with a repeat surrounding
the table rows. Each rows contains the input controls to fill in the
data for the specific request, and a trigger to issue a xforms:insert
that adds another empty request fragment.

Here's the documentation regarding xforms:repeat:
http://www.orbeon.com/ops/doc/reference-xforms-ng#xforms-repeat

There are some examples with source code in the xforms sandbox:

(select the "Test Samples" tab and select one of the examples from the
combo box).
