Not able to set custom aspect property on document

[kartech11]

Hi, 

I am currently using CMIS to create documents. I see lot of examples that update for aspect properties or custom properties on the document by updating the properties map and passing it to createDocument API

Do these documents need to have any aspect associated upfront before I set a custom property? 

I am currently setting a custom property but I get the below error

ObjectId idOfCheckedOutDocument = currentDocument.checkOut();
pwc = (Document) session.getObject(idOfCheckedOutDocument);
ByteArrayInputStream stream = new ByteArrayInputStream(newContent);
ContentStream contentStream = session.getObjectFactory().createContentStream(documentName, Long.valueOf(newContent.length), mimeType, stream);
ObjectId objectId = pwc.checkIn(true, properties, contentStream, "New version of document");

I had set the properties map with a custom property but I get the below exception . Is this because an aspect type s not associated to the document at some hierarchy?

Exception in thread "main" java.lang.IllegalArgumentException: Property 'myaspect:docStatus' is not valid for this type or one of the secondary types!

Thanks

You must set the secondary type (aspect) before setting the properties.

Hi Angel Borroy‌ - Thanks a lot for the link.

What will happen if I have two secondary types with different namespace but the same property name. In the below example from the link that you have provided, the secondary type gets added with namespaceropertyname but when the property is set it is set without the namespace. So if I have two namespace custom1 and custom2 and they have property called classification, how do I set it in the properties for both these namespaces

Map<String, Object> properties = new HashMap<String, Object>();

// add the new secondary type

secondaryTypes.add("custom:classification");

properties.put(PropertyIds.SECONDARY_OBJECT_TYPE_IDS, secondaryTypes); // set secondary type property

properties.put("classification", "public");

[angelborroy · Accepted solution]

Add also your prefix to property name, something like "custom:classification"

This is how I am doing while uploading a document with properties. Sometimes the version of CMIS API might matter to the way we do things. I am using CMIS 1.1

My pom dependency

<dependency>
<groupId>org.apache.chemistry.opencmis</groupId>
<artifactId>chemistry-opencmis-client-api</artifactId>
<version>0.13.0</version>
</dependency>

And my CMIS API endpoint

ttp://alfresco-server:8180/alfresco/api/-default-/public/cmis/versions/1.1/atom

Code extract:

HashMap<String, Object> cmisDocumentProperties = new HashMap<String, Object>();

cmisDocumentProperties.put("cmisbjectTypeId", "D:slo:mdocument");

          List<String> secondaryTypes = new ArrayList<String>();
         secondaryTypes.add("P:slo:documentProperties");
cmisDocumentProperties.put("cmis:secondaryObjectTypeIds", secondaryTypes);

cmisDocumentProperties.put("slo:m_link", value);
cmisDocumentProperties.put("slo:m_category", value);

InputStream stream = null;
byte[] content = mDocument.getBData();
stream = new ByteArrayInputStream(content);
ContentStream contentStream = cmisSession.getObjectFactory().createContentStream(
mDocument.getFileName(), Long.valueOf(content.length), mimeType, stream);
insertedDocument = entityFolder.createDocument(cmisDocumentProperties, contentStream, VersioningState.MAJOR);

My custom model xml:

<types>
<!-- custom document type -->
<type name="slo:mdocument">
<title>SLO Document type</title>
<parent>cm:content</parent>

<!-- associations section - no associations as of now -->
<!-- aspect is defined to hold all the properties -->
<mandatory-aspects>
<aspect>slo:documentProperties</aspect>
</mandatory-aspects>
</type>

</types>

<aspects>
<!-- There is one aspect with all the custom properties defined -->
<aspect name="slo:documentProperties">
<title>m document properties</title>
<properties>

<property name="slo:m_category">
<title>Category</title>
<type>d:text</type>

</property>
<property name="slo:m_link">
<title>Link ID</title>
<type>d:int</type>
</property>

....

Hope this helps.
