I've got ckeditor attached to a plugins flexforms field. Each time the plugin (ce) is saved, empty paragraphs are added for newlines and <br> are converted to <p> </p>. No flux or dce in use. TYPO3 is 8.7.13 (and current 9 as well). Just a plugin using pi_flexform with a rte field like this:
<settings.bookingConfirmationEmailBody>
<config>
<type>text</type>
<rows>5</rows>
<cols>30</cols>
<eval>trim,required</eval>
<enableRichtext>1</enableRichtext>
<richtextConfiguration>exhibitors_email</richtextConfiguration>
</config>
</settings.bookingConfirmationEmailBody>
I figured out, that on direction "from rte to db", eveything is stored correctly. But "from db to rte", newlines and <br> are converted to <p> </p>, which multiplies each time i save. Already spent hours on this :(
