Question

Is there some way to derive field values from other fields in Orbeon CE with the help of perhaps some xml script?

I would like it to take some fields as in-parameters, do some calculations and then produce an out-parameter to put in a non-editable field.

I am assuming that this is for a form you’re creating with Form Builder. If this is the case:

1. Name the “input” field, by clicking on the gear icon and typing a name. Say first-name.
2. Create a text output field, click on the validation settings icon next to the field, and in the dialog, in Calculated Value, type an XPath expression, say: concat('Hello ', $first-name, '!'). As you can see from this example, you can use the $gaga variable to refer to the field named gaga.
