i have setup a SOAP web service to auto populate some of the field in my form, but one of the fields I would like to auto populate is based on a Person/Group Picker.  The only rule I am able to apply is format but I need to apply an action, is there anyway of doing this?

What I want to happen:

the originator select a person via Person/Group Picker and the following rule is run after the name have been confirmed

set "web service input" to "Person Picker"

Query web service

Set form field to query

I think you can workaround this by adding an temp field on your form.  Set the default value of your temp field to AccountID and then create your action rules off this temp field.  This should work for the single person case.  You'll have to play around with it if you need this to work for the multiple selection case.
