I am getting the same error message with the current trunk as of today.
Created a new node and added the "mix:versionable" mixable.
fileNode = folderNode.addNode(filename, "nt:file");
if (fileNode.canAddMixin("mix:referenceable"))
fileNode.addMixin("mix:referenceable");
if (fileNode.canAddMixin("mix:versionable"))
fileNode.addMixin("mix:versionable");
// if (fileNode.canAddMixin("mix:simpleVersionable"))
fileNode.addMixin("mix:simpleVersionable");
Error:
org.springframework.web.util.NestedServletException: Request processing
failed; nested exception is javax.jcr.nodetype.ConstraintViolationException:
OakConstraint0021: /documents/versiontest3.jpg[[nt:file, mix:referenceable,
mix:versionable]]: Mandatory property jcr:predecessors not found in a new
node
(However, I don't get the message if I add the "mix:simpleVersionable"
instead, which makes sense though since it does not seem to be implemented
according to https://issues.apache.org/jira/browse/OAK-4166: "As a result,
versioning-related methods invoked on such [simpleVersionable] nodes doesn't
work correctly.)
I looked up the definition:
https://docs.adobe.com/content/docs/en/spec/jcr/2.0/15_Versioning.html
"Under both simple and full versioning, on persist of a new versionable node
N that neither corresponds nor shares with an existing node:
Additionally, under full versioning:
The multi-value REFERENCE property jcr:predecessors of N is initialized to
contain a single identifier, that of V0 (the same as jcr:baseVersion)."
Now I am wondering, should all this (initialization of the jcr:predecessors
property) not be handled by the repository automatically in both cases,
since it knows whether this is a new node etc.? Is it a bug?
I found Jira tickets related to versioning, but they are already three years
old and set to resolved.
