Assigning a value to a global binding

Question

I'm using a Global binding for a header field called ReportClassification. It ensures that if the user changes the value of the field, all the fields will be kept in sync.
How do I pre-assign a value to the global so that the fields wil be pre-populated? I thought about having an initialize event that does the following :
global.ReportClassification="UNCLASSIFIED";
Doesn't seem to do anything.

Yep. I'm still using Javascript. Maybe I need to understand how the Master Page fields are referenced from Pages. Essentially I can change the value of a master field from the master page field's initialize method. When I try to change it from the page (eg. in the pages initialize method or when the OK button is pressed on the dialog and the commit method is called) it doesn't update. There is no error but it just doesn't change.
I've tried alerting the element from the commit method and I can get the element's value. I just can't set it. Is there some security issue doing on there. You can't change a master field value from a page.
eg. In the commit method or in the initialize method of the page.
app.alert("element="+ReportForm.pageSet.Page1.Header.ReportClassification);
- returns [object XFAObject]
app.alert("element.rawValue="+ReportForm.pageSet.Page1.Header.ReportClassification.rawValu e);
- returns UNCLASSIFIED
ReportForm.pageSet.Page1.Header.ReportClassification.rawValue="SOMETHING ELSE";
- no change in the value
