TYPO3 Core

css_styled_content is selected (which is the current version). Are you using the current master or beta5?

The problem is the listNum seperator.

The function TYPO3\CMS\Core\Resource\Service\FrontendContentAdapterService::modifyDBRow modifies some db fields.
Now the tt_content column image_link contains the sys_file_reference.link values seperated with a newline.
The default seperator of the listNum function in TYPO3\CMS\Frontend\ContentObject\ContentObjectRenderer is a ',' .
The css_styled_content typoscript don't define a newline as splitChar for listNum,
so the listNum function can't convert the image_link column as an array and parsed the links incorrect.

It works if i define the splitChar with

tt_content.image.20.1.imageLinkWrap.enable.ifEmpty.typolink.parameter.listNum.splitChar = 10
tt_content.image.20.1.imageLinkWrap.typolink.parameter.override.listNum.splitChar = 10

(i used the beta7 core and the current css_styled_content)

I can not reproduce. Could it be you are not using the latest css_styled_content?

here the typoscript looks like:

tt_content.image.20.1.imageLinkWrap.enable.ifEmpty.typolink.parameter.data = file:current:link
tt_content.image.20.1.imageLinkWrap.typolink.parameter.data = file:current:link

The listNum.splitChar sounds like a fallback to the old rendering.

Ok, sorry. A extension merged some listNum stuff into the Typoscript and generate this error.
By default, TYPO3 works correctly.
This issue can be closed.
Thanks.
