You have to address the specific parent/sibling structure.
Julian was giving an example.

Look at the layout.

icon.parentNode.getChildByName(“protoPage”).duplicate(templateData.presentation[0].page.length 
- 1);

parentNode of makePages = Learning Object

Does Learning Object have a direct child called 'protoPage'? No.

Try this:

icon.nextSibling.getChildByName('protoPage').duplicate(templateData.presentation[0].page.length - 1);

Because the makePages nextSibling (Interface) has a direct child named protoPage

So your pages will be duplicated. But other things will appear undefined as they are also making relative position assumptions that no longer hold.

Thank you, but still it doesn't work.
I tried both in the origanal template without the 
entryframe: 

icon.parentnode.getChildByID("proto").duplicate(templateData.presentation[0].page.length 
- 1); (I gave the icon an ID 
"proto"
icon.parentNode.getChildByName(“protoPage”).duplicate(templateData.presentation[0].page.length 
- 1);

I only get the first page with correct text. But 
there are 3 pages.
:(

  You 
  can also use getChildByID()

  Use 
  getChildByName() to avoid having to know the structure / number of 
  children.

  Much 
  better to say icon.parentNode.getChildByName(“myProtoPageName”) than to say 
  icon.nextSibling() etc where if the structure changes, so does your 
  code,

  Thank you 
  Dave,

  I am a bit further 
  now. But still have some trouble.

  Now I have 
  :

  the make pages 
  icon, then the interface icon, the interface icon contains an entry frame, and 
  the protopage. So I addes only an entry frame.

  I made 3 pages with 
  the template

  I changed the code 
  in the makepagesicon into: 

  icon.nextSibling.childNodes[2].duplicate(templateData.presentation[0].page.length 
  - 1);

  icon.nextSibling.attributes.title 
  = templateData.presentation[0].name;

  //set the page 
  titles
for (i = 0; i < 
  templateData.presentation[0].page.length; i++){

  icon.nextSibling.childNodes[i].attributes.title = 
  templateData.presentation[0].page[i].name;
}

  If I preview the 
  presentation and I got only one page: Page 2. It contains the right text 
  and picture but there should be 3 pages.

  Then  I 
  changed 

  icon.nextSibling.childNodes[2].duplicate(templateData.presentation[0].page.length 
  - 1); 

  into 

  icon.nextSibling.childNodes[1].duplicate(templateData.presentation[0].page.length 
  - 1);

  Then with 
  previewing I got 3 pages,  it doesn't show page 1, then it shows 
  page 2 and 3 (with correct pictures and text) and then it shows a page 
  undefined.

  I should think 
  icon.nextSibling.childNodes[2] 
  is the protoPage? But why doesn't that work? and why do I get some result 
  with icon.nextSibling.childNodes[1]? And why I don't get 
  page 1 then?

You have to 
    be very careful around template architecture.

You see the script icon 
    above the Interface icon called makePages?
Open it up and look at the 
    first line of 
    code.

icon.nextSibling.firstChild.duplicate(templateData.presentation[0].page.length 
    - 1);

That is making the pages of your presentation:

icon = 
    here, this icon
nextSibling = next icon downward
firstChild = next 
    icon rightward
duplicate = duplicate

So it is saying, duplicate 
    the protoPage icon x number of times.

When you insert your entry pane 
    on to the Interface page, you have inserted a sibling between makePages and 
    the target, protoPage.
So the relative logic is destroyed and the piece 
    is not being built.

You would have to adjust all the relative 
    references in the piece to take into account the added entrypane 
    icon.

Subject: [Xerte] simple 
    presentation

    Hi, I am very new 
    in Xerte.

    I am trying to 
    understand the simple presentation template.

    I would like 
    to ad an entry frame to the interface icon and then add som cusom 
    buttons.

    However, when 
    I insert an entry frame,  the application doesn't work correctly 
    anymore. The text icon shows 'undefined' and I cannot go through the 
    pages.

    What I am doing 
    wrong?

    Thanks for any 
    help
