Hi, how to extends base behaviour of versioning ?
I need two more properties on Version :
comment (String) - simple description of something interesting with version
authorId (String) - id of user witch performed checkin.
With normal Node it's simple - custom node type. Is there any way to do
something like that:
<nodeType name="type:version" isMixin="false"
hasOrderableChildNodes="false" >
<supertypes>
<supertype>nt:version</supertype>
</supertypes>
<propertyDefinition name="ext:comment" requiredType="String"
autoCreated="false" mandatory="false" onParentVersion="COPY"
protected="false" multiple="false" />
<propertyDefinition name="ext:authorId" requiredType="String"
autoCreated="false" mandatory="false" onParentVersion="COPY"
protected="false" multiple="false" />
</nodeType>
Thanks,
Martin

Hi,
suggested API:
void checkin(String absPath, Object versionableEntity, String[]
newVersionNumbers) throws LockedException;
void checkout(String absPath, Object versionableEntity) throws
LockedException;
String[] getVersionLabels(String absPath, Object cmsObject);
void addVersionLabel(String absPath, Object entity, String versionLabel);
and (maybe) working implementation:
public void checkin(final String absPath, final Object
versionableEntity, final String[] newVersionNumbers) throws
LockedException {
try {
Node node = getNode(absPath);
checkIfNodeLocked(absPath);
Version newVersion = node.checkin();
VersionHistory versionHistory = node.getVersionHistory();
if (newVersionNumbers != null) {
for (int i = 0; i < newVersionNumbers.length; i++) {
String versionLabel = newVersionNumbers[i];
versionHistory.addVersionLabel(newVersion.getName(), versionLabel,
false);
}
}
} catch (UnsupportedRepositoryOperationException e) {
// This catch UnsupportedRepositoryOperationException potentionally
throwed with Node.checkout()
// indicates that node is not versionable - it means coding bug in

not mix:versionable. Path: " + absPath, e);
} catch (RepositoryException e) {
// This typically 'If another error occurs'.
throw new
org.apache.portals.graffito.jcr.exception.RepositoryException("Unknown
error on checkin: ", e);
}
}
public void checkout(final String absPath, final Object

throw new
org.apache.portals.graffito.jcr.exception.RepositoryException("Unknown

public String[] getVersionLabels(final String absPath, final Object

VersionIterator versionIterator = vh.getAllVersions();

Hi all,
I'm still working on the JCR integration and I'm wondering what are our
needs in point of view content versionning ?
I would like to start with simple use cases but I want to know if
someone
has specific requirements.
Furthermore, how do you see the versionning API in the JCR-mapping
subproject ?
Do we create a new component (like the QueryManager) or add new
methods in
the PersistenceManager ?
All ideas, comments, thoughts are welcome.
kind regards,
Christophe
