Problem with custom Aspects (CMIS Policy)

jawwad

Hi,

I just created a custom model (book) in Alfresco 3.4.1. It includes a type b:bookType and an aspect b:bookPublication. Now both are present in the repository with the names D:b:bookType (a content type under cmis:document) and P:b:bookPublication (under cmisolicy)respectively. The D:b:bookType works fine but I cant figure out how to use the P:b:bookPublication. coz when i try to create a new policy using:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;properties.put(PropertyIds.OBJECT_TYPE_ID, BaseTypeId.CMIS_POLICY.value());
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;properties.put(PropertyIds.NAME, policyType.getId());
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Policy policy = customFolder.createPolicy(properties);‍‍‍‍‍

it returns error: Exception in thread "main" java.lang.IllegalArgumentException: Property +'cmis

bjectTypeId' is not valid for this type!

and I cant find a way to retrieve it as a Policy object. So plz can anyone tell me what should I do or what am I doing wrong?

Any help will be highly appreciated. Thanks in advance.

Hi Jawwad,

The Alfresco OpenCMIS Extension gives you access to aspects: http://apache-extras.org/p/alfresco-opencmis-extension

Hi and Thanks Florian,

I tried the Alfresco OpenCMIS Extension but now im having a class cast exception. My code is:

Document existingBook = (Document)session.getObject(bookTypeDoc);
      AlfrescoDocument alfDoc = (AlfrescoDocument)existingBook;
      alfDoc.addAspect("P:b:bookPublication");
      if(alfDoc.hasAspect("P:b:bookPublication")){
         properties.put("b:publishedBy", "Custom CMIS");
         alfDoc.updateProperties(properties);
      }‍‍‍‍‍‍‍

Here the Document im retrieving is of a custom type (D:b:bookType). and the exception is:
"
Exception in thread "main" java.lang.ClassCastException: org.apache.chemistry.opencmis.client.runtime.DocumentImpl cannot be cast to org.alfresco.cmis.client.AlfrescoDocument"
On this code

AlfrescoDocument alfDoc = (AlfrescoDocument)existingBook;‍

Same happens when I try to cast a general non-custom type. Can you plz help me on this?

Thanks in advance.

Hi,

Sorry, I found my mistake

. I was missing this session parameter entry.

params.put(SessionParameter.OBJECT_FACTORY_CLASS, "org.alfresco.cmis.client.impl.AlfrescoObjectFactoryImpl");‍

Thanks again
