Hi Christian
Thank you for your answer.
String pmv = ivy.cms.findContentObjectValue(String,java.util.Locale).getProcessModelVersion().toString()
With this Information it is possible to determine, from which project the content comes from.
if(!pmv.matches(".*foo_bar\\$.*")) {
//ivy.log.info("multitenant and content //ivy.log.info("content object from override");
In that case, the user can change the Value in his own cms.
Cheers
Andreas
