[TYPO3-dam] isReadOnlyFolder function missing ?

[Thomas Oppelt]

Hi guys,

T3 4.2.1
dam/trunk at revision 12644 (= up to date)
dam_ttcontent/trunk at revision 12644 (= up to date)
gives me a:
Fatal error: Call to undefined method 
tx_dam_browse_media::isReadOnlyFolder() in 
/var/www/vhosts/.../typo3conf/ext/dam/class.tx_dam_browse_media.php on 
line 340

when opening wizard for file selection within tt_content ce image fields.

regards
tom
