[TYPO3] Dummy Installation 4.2.1 + rte in a frontend-plugin + linebreaks will be lost after saving the page

[Konrad Schiertz]

Hello Andreas,

standard content element = Regular text element

frontend-plugin = my own small frontend-plugin created with the 
extension manager


Creating paragraphs is no problem, but after saving the page the 
paragraphs in my frontend-plugin rte are lost. I can't realize why?
