If I have a text control that is hidden when I use a form rule to update the value the control is not updated. It works if I leave the control visible. This is also the same if the control is visible but is in a group that is marked as hidden.

I have a variable that is populated with the function getQueryStringParameter

I have the following form rule:

When a variable is filled

then set a group to visible

else

set textcontrol value to newGuidAsString()

I thought a rule would be able to update a control value even if the control is hidden?
