So, after an IRC-session in #typo3@chat.freenode.net the guys (kudos to @cedricziel and @amkoroew) and I figured out that first of all the TER-versions of EXT:flux
and EXT:fluidcontent
are not working, but those from GitHub are:
The path to the template files needs to abide the default extbase convention, i.e. EXT:myext/Resources/Private/Templates/Content/myFCE.html
(There is a way to use a non-standard path, but I haven't tried it)
EXT:fluidcontent
also expects the TypoScript-setup to be as follows:
plugin {
tx_myext {
view {
label = Fluid Content Elements
extensionKey = myext
templateRootPath = EXT:myext/Resources/Private/Templates
}
}
}
After updating the extensions and moving the file to its new location, the FCE works as expected.
