How to remove all pages from layout? (except Master Page)

Question

Geetings Experts:
I'm implementing additional security measures into my 'initialze' event, where I'll check some global variables and render the file unreadable if needed.
Which object and properties do I access to remove all my pages from the form?
I would like to createa a function that removes all the sub pages, leavning only the Matster Page, enable a label in the MasterPage and save itself.
I searched for xfa.layout and Page[n].remove() methods but cannot find any reference to these.
.presence = "hidden", fulfills my purpose but the pages remian visible and I need for a clean solution no pages are visible.
I'm advanced in C# but a novice in LC JavaScript, so any comment, reference or code snipet will be greatly appreciated
Thank you for your time,

Hi Ivan,
The particular syntax of Javascript in LC Designer is different from that used in Acrobat and different (as I understand it) from core javascript and other applications. There are several free guides on the Adobe web site which cover Acrobat and LC:
http://www.adobe.com/go/learn_lc_scriptingBasics
http://www.adobe.com/go/learn_lc_scriptingReference
http://www.adobe.com/go/learn_lc_formCalc
http://www.adobe.com/devnet/livecycle/articles/Adobe_XML_Form_Object_Model_Refer ence.pdf
http://www.adobe.com/devnet/acrobat/pdfs/lc_migrating_acrobat_xmlform.pdf
And a very handy resource (it goes back to version 6, but is still applicable):http://partners.adobe.com/public/developer/en/tips/CalcScripts.pdf
JP Terry's book on LC Forms is very good and we use www.pdfscripting (which is a subscription service). If you are going to be doing a lot of LC Designer work, these may be of help.
I am not a coder, so I going to try and work through your script. Bear with me if you already have this sorted...
The script looks ok and you are using the resolveNode method correctly. Seeing topmostSubform in the resolveNode indicates that you imported an existing document into LC. This is fine, but sometimes it restricts some of the functionality.
For starters I think that mPg is returning null. You can use the following in your script to see what is happening (debugging) and then comment it out:
console.println("mpg: " + mPg);
Then when previewing hit control+J to bring up the javascript console, then will show the value of mPg when that script executes.
Try deleting the SOM up to #pageSet:
var mPg = xfa.resolveNode("#pageSet.MasterPage1");
The javascript console will show you when the script is working.
In relation to the loop, I would advise a few changes:
for (var i=1; i <= xfa.layout.pageCount(); i++)
     var vPage = ("xfa.form.topmostSubform.Page" + i).toString();
     //console.println("vPage: " + vPage);
     var curPage = xfa.resolveNode(vPage);
     curPage.presence = "hidden"; 
}//next page
There are a few things here:
I would declare i as a variable, not an integer (not sure if it makes a difference);
I would use pageCount rather than numPages and then <=;
There was an extra ; at the end of the loop declaration;
I would break the script into steps and get the full SOM of the page as a variable first and then resolveNode that variable;
You don't need to go to the current page;
I tend to name master pages with a capital "P" and pages with a small "p". Personal preference, but it can make tracking script easier.
Have a crack off that and hopefully you can get it to work,
Niall
ps another tip, if you want to reference an object in script. First click on the object you want to script for and then scroll (or click on the master page) for the object you want to reference. Click inside the script editor and then when you move the mouse back into the form, press and hold Control, this will turn the mouse into a "V". When you click on the object you want to reference it will insert the SOM into the script. If it needs the resolveNode it will automatically put that in for you. Holding Shift and Control will insert a fully resolved node.
