Orbeon Form Builder 4.4 - can database services & actions work with repeats?

Question

Say we have a form built in Form Builder that consists of one repeat, containing two controls: a text input (id) and a text output (name). In addition we have a populated database table with two columns, id & name.

This is how the form should behave: the user can add as many rows as needed. In each row, when an ID is entered for a row, a database service is called which looks up name for the given id, and the Name text output is populated on that row.

It's easy to get such a scheme to work if a repeat isn't involved, but with the repeat, it seems that Orbeon doesn't know from which row to get the id parameter value, or to set the returned name value. Any options for accomplishing this that would work in Form Builder?

Answer 1

Apparently the answer is "no" for 4.4 but forthcoming v4.5 should introduce actions that work with repeats (see here and here).
