Updated text field in master page does not display actualized on all pages

[monty158cl201]

Hi everybody,

I am currently creating a form using LiveCycle Designer ES4 Version 11. Purpose it to have it opened, filled-out, printed, saved, etc... by other colleagues working with Adobe Acrobat Reader DC.

Since the form can have quite a few pages depending on how complex the described situation will be, I wanted to repeat in the header a few commons things to the form so that if a printed page get lost, anybody could identify quite fast to which project, task, client, etc... it belongs.

I created for that a master page "MasterPage2" with 2 text fields (read only) in the header position ...

...and on the the first page of the form "Page1", some other editable text fields.

I built some actions so that on change of those editable text fields (on "Page1"), the header text fields on the "MasterPage2" are actualized. I was expecting that "Page2" and "Page3" using the "MasterPage2" are getting their header actualized.

When I fill up those fields in Acrobat Reader...

...the header on page 2 is updated accordingly...

but for page 3, the text headers remain empty...

Can somebody explain me what I did wrong and help me fix this?

Thanks for your help !
