Layout accessing parent from attached url

Suite and Optimus Suite 5

Hi,

Requests
I am wondering if it possible for the team to provide the full example about accessing parent from attached page that showed on this page:
https://docs.dhtmlx.com/layout__attach_urls.html#accessingparentfromattachedpage

Question
I have three files, they are layout.html (dhtmlx layout), gantt.html (dhtmlx gantt), map.html (bing map). I have a layout with two cells in layout.html. I attached map.html to cell a and gantt.html to cell b by . Q1: What I want to do is click a button in map.html(cell a) to change the title of cell b and refresh the gantt.html (cell b). Q2: Why the horizontal scroll bar of gantt chart is missing after attached to layout. How can I get it back?

Code
Currently, I have constructed my layout inside layout.html like this:

function doOnLoad() {
pile_layout = new dhtmlXLayoutObject({
parent: document.body,
pattern: “3L”
});
pile_layout.cells(‘c’).attachURL(‘map.html’)

Inside my map.html I have a button and a function like this:

input type=“button” value=“change title” onclick="change_title()
function change_title() {
document.body.pile_layout.cells(‘c’).setText(‘123’);
}

Current Situation
However it seems like the child page can not find the layout in the parent page.
Therefore, I am thinking that a full example about accessing parent from attached page could help.

Thanks
LL

Please, try to use the

parent.pile_layout.cells(‘c’).setText(‘123’);

instead of

document.body.pile_layout.cells(‘c’).setText(‘123’);

just like it is mentioned in the docs.
If the problem still occurs for you please, provide a complete demo or a demo link, where the problem can be reproduced locally.
