control-setvalue action
Availability
Introduction
The control-setvalue process action sets the value of a form control.
This process action matches the semantic of the <fr:control-setvalue> action in the action syntax.

valuethe value expression is evaluated in the context of the root element of the form data and the resulting value is set on the control
you can use the
$foosyntax to refer to the value of another control, wherefoois the name of that control in the same scope (i.e. in the same section template instance, or at the top level if not in a section template)
section-namespecifies the name of a form section identifying one or more (in case of repeated sections) section template instances included in the form

Examples
Set the value of a top-level form control called contact-information-first-name to the value "Homer":
Set the value of a top-level repeated form control, on the first repetition:
Set the value of a top-level repeated form control, on the second repetition:
Set the value of a top-level repeated form control, on the last repetition:
Set the value of all repetitions of a top-level repeated form control:
Set the value of a set of form controls in a section template, by specifying the section name address-us:
The above actions can result in the following values in a test form, if combined in the following process for application my-app and form my-form, in new mode, and executed after controls are processed:

Set the value of a top-level form control called second-control with the value from a first control called first-control:
Earlier Orbeon Forms versions
With Orbeon Forms 2025.0 and earlier, you have to use the lower-level xf:setvalue action to set the value of a control. The drawback is this is that you have to directly reach data in the XML document containing all of the form data. The new control-setvalue action allows you to set the value of a control without having to know where in the XML document the data for that control is stored.
