TYPO3 Core

Hello,

I have created a 6.2.5 Website last year. On this website I use the content slide feature:

content_bottom_bottom < styles.content.get
content_bottom_bottom.select.where = colPos=4
content_bottom_bottom.slide = -1
content_bottom_bottom.slide.collect = -1

It all worked well - until I upgraded to 7.2. All the sudden the website wasn't working any longer, and I boiled the error down to one line:

content_bottom_bottom.slide.collect = -1

I have seven content blocks which use the slide feature, so this line (with a different variable) appears seven times in my code. With those lines active my frontend turns into an infinite loop of waiting (not even the 240 seconds PHP execution time, but literally infinite!).

Removing slide.collect seemed to work fine at first, but logically it means that inherited content won't be displayed if the block has its own content (which is what I need). I figured, since -1 means that TYPO3 will collect content all the way up to the root element, I could set it to 5 to reflect the amount of layers I have to the root element. That seemed to work as well, but it had the following effects:

I have a layout like this:

Root
- Website (Shortcut to Homepage, contains a few content blocks which are inherited by EVERY page)
- - Homepage (Contains a block which is inherited by selected pages)
- - - Imprint (inherits the footer from "Website"
- - - ...
- - - Some page (is deactivated, but required so .slide works, since sysfolder breaks it)
- - - - Subpage which inherits the footer from "Website" and the single block from "Homepage"

Case A: Subpage

I inserted a divider to "content_bottom_bottom". Instead of displaying it like this:

------------------
Inherited content

I got this:

------------------
Inherited content
------------------

So the additional content is added above AND below the inherited content.
Everything else was fine.

Case B: Homepage

Each element of the footer (from "Website") appeared two times:

A1      A2
A1      A2

A3  A4  A5
A3  A4  A5

And the single element that is inherited to selected subpages appears three (!) times!

Case C: Imprint

Everything works fine. Just like "Subpage" the footer only appeared once. Since it doesn't inherit the block of "Homepage" (unlike "Subpage") there was no other problem.

I decided to try older version of the 7.x-branch. I started with 7.0.0, and here everything worked fine: I was even able to set .slide.collect back to -1, so my extension was identical to how it works in the 6.2.5 live installation. Then I tried it with 7.1.0 - and it stopped working. Same behaviour as 7.2!

My testing machine is a Debian 8 virtual machine with Apache and PHP 5.6.7. A test on Windows Vista + PHP 5.5 with TYPO3 Version 7.2 brought up the same result.
