Why are global variables accessible from a different PDF?

Hi.

Can anyone please help.

When I set a Global Variable in Document 1, I can access this Global Variable in Document 2 if Document 1 is still open.

Why is this, I thought this was stopped by Adobe for Security Reasons?

Kind regards

Jon

That's the entire point of a global variable... Use a doc-level variable

instead.

There are two options if you want data to remain persistent with in a document context.

1. Write the data to a form field, that is what they are good for.

2. Write the data to the "info" object. This is the same as the data set on the "Custom" tab on the document properties dialog

It depends on how things are set up on the system the PDFs are being used on. For example: Edit > Preferences > JavaScript > Enable global object security policy

I have tried that setting and am still having the same issue.

Is there any other way to save a variable in a document that can be accessed in the future, without using the Global object. Or am I just using it wrong?

Thanks for the speedy reply, much appreciated.

The easiest way to save a value in a document is to set the value of a form field, which can be hidden or on a hidden template page. It's hard to say why you're having the problem you are without knowing exactly what you're doing.
