Is this a bug or am I missing something???

Update, I've added an alert box to display the pageNum to make sure that wasn't the problem. The weird thing is that when the script executes, the correct number (4) is shown, and the correct page is shown (4). It is not until after the dialog is accepted that the doc jumps to pageNum=3.

There are no other scripts in this document.

The pageNum property is 0-based, so if you are on page 4 pageNum is 3, not 4.

Thanks, yes I'm aware of the zero based page numbering, the problem is that it is not respecting it on the page being called i.e. if the button is on page 5 (pageNum=4), it is going to page 4 (pageNum=3) for some reason.

Paste the exact code you're using. Maybe that will help debug your problem.

Thanks try67 and sorry about the delayed reply. I have tried a number of things to get this to work and was trying to debug with the simplest possible script in a button which is this:

this.layout = "SinglePage";
this.pageNum=4;

My ultimate goal to to have a document script that would toggle the view but have had no success.

here is what I was working with, I can create a simple example pdf if that would be helpful:

function toggleZoom()
{
var docLayout = this.layout;

if (docLayout == "SinglePage")
{

this.layout ="TwoPageRight";
this.zoomType = zoomtype.fitW;
}
else
{

this.layout ="SinglePage";
this.zoomType = zoomtype.fitW;

}


}


Thanks again,
Rob

The script you posted works just fine for me (from the console).

Thanks, I've created a small (5 page) example pdf and uploaded it to http://www.robject.com/toggleTest2.pdf

I've added comments in the document script and the buttons themselves but in a nutshell, the toggleZoom function always returns the left facing page while the "this.pageNum=2;" works on all pages except "pageNum=2" which returns "this.pageNum=1;"

Thanks again for your help,
Rob
