Description Ulrich Windl 2013-10-07 08:10:34 UTC
When viewing a document with two windows (additional view), the following problem is observed: When changing the view type (e.g. form single page to side-by-side pages) in one view, the other view also changes.
This is not what the user expects.
Comment 1 Ulrich Windl 2013-10-07 08:13:07 UTC
Problem is also present in 4.0.5.2.
Comment 2 Yousuf Philips (jay) (retired) 2014-06-07 16:05:25 UTC
Dear Ulrichi,

I dont quite understand the issue as LibreOffice has two views, Print Layout and Web Layout and in Web Layout you can change the view from single page to side-by-side view.
Comment 3 Yousuf Philips (jay) (retired) 2014-06-07 16:25:08 UTC
If you could send some screenshots, that would also be helpful.
Comment 4 Ulrich Windl 2014-06-10 07:28:55 UTC
I just checked: I'm always using the print layout. See also bug 71775.
Comment 5 Yousuf Philips (jay) (retired) 2014-06-10 09:38:55 UTC
So is 71775 a duplicate of this one? I checked its details and it seems you left quite alot out of this reporting. Can you attach the 1.4mb file here so i can see it. I dont see how you can modify the same file at the same time when one of them should be having a lock on the file. If you say you were modify two different files, that would be more understandable.

Attached for bug 71775 (https://bugs.freedesktop.org/attachment.cgi?id=100795), because it is more related to that bug.

Yes i see the page jumping from the page numbers. By the way, which screen recorder did you use.

Confirmed in Linux Mint in 3.3.0, 4.2.4 and 4.3 beta.

Steps:
1. open http://www.libreoffice.org/assets/Uploads/EN-Documents/Installingextensions.odt
2. set the page view to side-by-side
3. zoom out so you can see two pages side-by-side
4. scroll down to page 7 (status bar as 'Page 7 / 8')
5. press single page view
6. it jumps to 'Page 4 / 8'

I was using "Corel ScreenCap X6" from Corel Video Studio X6, because that's the only tool I have to do it.

two window view of same document

I think this was what the OP was experiencing in the other bug.
1. Opened document.
2. Window -> New Window.
3. Switch to other window.
4. Change page view to Two-page view and zoom out.
Result:
Window loops between single-page view and two-page view.

What it looks like is happening in comment 7 is that page 7 is the fourth page down from the top and when switching back to single-page view it keeps it at the fourth page down which is page 4.  If you have it on page 5 in two-page view then it will put you on page 3 when switching back to single-page view.

The problem still exists.
Comment 13 V Stuart Foote 2016-10-04 13:23:12 UTC
Seems that when recomposing the document canvas, we don't reposition the view of the canvas to match the text cursor. Nor do we reposition the view indexed to the last page in view before changing.

Instead the positioning of the view seems arbitrary. I'm sure it is not and concur with observation in comment 10, but some adjustment is needed to index to either the text cursor, or the page in focus prior to changing the view -- Single Page-Multi-Page-Book

@Kendy, similar ViewShell canvas positioning issues during autosave with bug 95797 and bug 41063 -- could the ViewShell be adjusted to have better logic for determining the page of the canvas with focus?  Perhaps provide an configurable option to force it to follow text cursor, and by default retain the focus on the page displayed when event fires.
Comment 14 Yousuf Philips (jay) (retired) 2016-10-04 16:04:04 UTC
As the zoom level is independent per window, it makes sense that the view type could also be independent per window, just like in calc being able to set one window to normal view and another to page break view, but we'd need dev input to see whether it is possible or was purposely done this way.

@Maxim: Any thoughts?

Obviously the bug was not fixed (in 5.3.6.1).

Most bugs do not "just magically go away"; it's still present in 6.4.7.2 (Windows 10)
Comment 21 Ulrich Windl 2020-10-26 08:22:05 UTC
Addition: I noticed when there are two open windows on one document, and you move the zoom slider in one window, the other window (i.e.: the view inside) also temporarily changes the size or changes position.
