control of an element placed on a masterpage

The master pages aren't really meant to have active content on them. It's supposed to be more of a static background.

But this doesn't mean that it can't be done. In LiveCycle Designer, display your master page. Select the field you are interested, or add the field to the master page. Then open up the Scripting window and select an event. The SOM path for the element will appear at the top of the script.

This is the path you need to use to access the element. Notice that it's down the "data" path in the "form" model. The funky looking "#pageSet[0]" name is the MasterPages node. On the hierarch window, select "Master Pages". Right click and select rename. To rename MasterPages to something else. As soon as you do this you'll see the name change in the elements SOM Path. Now you have a SOM path that can be used in JavaScript.

I must admit that it actually looks obvious, however it still doesn't work... Maybe I do something wrong. Just for the case - here's the line I want to execute upon a button click (button placed on a normal page):
xfa.form.data.MPs.MasterPage2.MPButton.presence = "hidden";
I changed the (MasterPages) node name to MPs. Maybe this MPButton must be contained in a SubForm (or it can be placed directly on a master page)?

I gave this a try and it worked for me, for a button directly on the master page. Did you save the form as Dynamic?

Yes, the form is saved as dynamic.

If the SOM Path is correct and the form is dynamic, then it should work. Have you checked the JavaScript console for errors?

Quite frankly, I have never used the JavaScript console so I'm not even sure how to use it...

Hi watson23,

An article on using the JavaScript Console can be found at-

Hope this helps,
