Outdated PHPDoc comment in AbstractTreeView
While making an old extension work in TYPO3 7.6 and 8, I found that behavior of the AbstractTreeView has changed between 7.6.
The description of the variable $makeHTML is outdated, as it describes a configuration option no longer existing:
/** * If TRUE, HTML code is also accumulated in ->tree array during rendering of the tree. * If 2, then also the icon prefix code (depthData) is stored * * @var int */ public $makeHTML = 1;
The variable is treated as a boolean since 7.6, the mentioned value of "2" does not have any effect, so the affected line should be removed.
Ideally, the variable should be converted to a boolean. But as it's a public variable, I assume this would be considered a breaking change, so please let me know if I should provide a patch set for that, too.
