Update Object Type

Hi all,

I use OpenCMIS 0.2 to connect to an Alfresco 3.4 repository.

I try to update the object type using the following code:

Map<String, Object> properties = new HashMap<String, Object>();
properties.put(PropertyIds.OBJECT_TYPE_ID, "D:" + ParkTypeIds.EMPLOYEE_DOCUMENT);
document.updateProperties(properties);

But this doesn't work. There is no exception, but the type doesn't change.
Is it possible to change the type after creation?

Kind regards, 

Mano Swerts

Hi Mano,

It is not planed for CMIS 1.1. So the CMIS specification will not support this within the next 3-4 years. Not many repositories support this behavior.
There are also no plans to support this in Alfresco through CMIS anytime soon.

So, yes, you have to create a new object.


Regards,

Florian

Hi Florian,

Thanks for the quick reply.

I understand that it is not logical to update the type, but in my case the object is of a parent type park:Document and I want to change it to the child type park:employeeDocument. So this is theoretically possible because the child only defines some extra fields.

Will this be possible in the future for parent-child types or is my only solution to create a new object of the child type and copy all property values?

Kind regards,

Mano

Hi Mano,

It is not possible to change the object type after creation.
OpenCMIS silently removes the property from the properties map because 
it is not valid for a property update.

Florian
