Multiple version creations while creating/updating

[satishvarmadand]

Hi,

How it is going o solve the problem for Update.

   When i try to update a file, i am using
Content contentRef = contentService.write(node, Constants.PROP_CONTENT, dataToUpdate, contentFormat);

But by calling this, it is creating a version. I want to disable version creation when i update a document as i want to make use of authoringService.createVersion()).

The reason is simple, i can get hold to the latest version that was created and i can find out the version label etc…  using
VersionResult res = authoringService.createVersion(predicate, versionComments, false)

But if i do both for the same update option, it end up creating 2 versions; one with contentService.write() & other with authoringService.createVersion().

One option is to use "remove aspect". But when i use this , this is removing the entire version chain. This is more of a serious problem. Is there any way to just hold of version creation when i call
contentService.write

Other option i have is

cml.setAddAspect(new CMLAddAspect[] { addVersionableAspect });
       
UpdateResult[] results = respositoryService.update(cml);

this will solve the problem, but i can not get hold to what version it created ( i want version label)… i can not get the versionObject in return type.

Any help would be appreciated.

Thanks,
-Satish

Hi,
I found the solution and posting here. This moght be helpful if anyone is searching for this

Here is the way .
1) Search for "contentModel.xml" file . This will be under tomcat/webapps/alfresco/WEB-INF/classes/alfresco/model/contentModel.xml
2) Look for "<aspect name="cm:versionable">" inside that and make "<property name="cm:initialVersion">" & "<property name="cm:autoVersion">"  as false.

By updating this, it wont add a version by default. Now you will get more control on when to add a version and you can do that by
VersionResult res = authoringService.createVersion(predicateVersion, ….versioncomments,  false);

We can get the versionLabel & other version properties from this returned object.

Thanks for this information. Anyway, I have one relating problem.

When I set <property name="cm:initialVersion">" & "<property name="cm:autoVersion">" as false, I've got an error on the first "check-in" I make.

Didin't you get this problem ?

But I think there's a risk that it can change alfresco's default behavior for example type cm:mlContainer is versionable. And you have to remember to change the war during upgrade - that sort of customization should be done not in the war
I'm setting properties initialVersion and autoVersion directly in my code just before update

In case anyone finds this helpfull, this is what I did..

Assuming you have created a file already, use the authoring service to checkout the file. Then use the content service to update that working copy, and check it back in forcing a major version.

You''ll need to get a reference to the file you want to work with…In this example Im dealing with the bytes of a file Im reading in.

// Add the versionable aspect to the document.  This will allows the content to be versioned
makeVersionable(repositoryService, contentReference);

// Use authoring service to checkout file, update content, then check back in with major revision
AuthoringServiceSoapBindingStub authoringService = WebServiceFactory.getAuthoringService();

// Checkout the document to update, placing the working document in the same folder
Predicate itemsToCheckOut = new Predicate(new Reference[]{contentReference}, null, null);
CheckoutResult checkOutResult = authoringService.checkout(itemsToCheckOut, null);

// Get a reference to the working copy
Reference workingCopyReference = checkOutResult.getWorkingCopies()[0];

// Update the content of the working copy
ContentFormat contentFormat = new ContentFormat(MIME_TYPE, "UTF-8");
contentService.write(workingCopyReference, Constants.PROP_CONTENT, bytearray, contentFormat);

// Now check the working copy in with a description of the change made that will be recorded in the version history
Predicate predicate = new Predicate(new Reference[]{workingCopyReference}, null, null);

NamedValue[] revisionType = new NamedValue[]{Utils.createNamedValue("versionType", "MAJOR")};
authoringService.checkin(predicate, revisionType, false);
