[TYPO3-english] public function render(array &$PA, \TYPO3\CMS\Backend\Form\FormEngine $pObj)

[Matthias Eberlein]

Hi TYPO3 Friends,
i use in old TYPO3-6.2 Extension this:

public function render(array &$PA, \TYPO3\CMS\Backend\Form\FormEngine $pObj) 

The basic script is from Xavier Perseguers

This ext works fine till TYPO3-7.2.
I'am a bit blind now to adapt this to run under TYPO3 7.6.
Somebody can give me a hint?

many thanks
Matthias
