Loading secondary types

BenceKovacs

Hi Everyone,

I'm using the Apache chemistry opencmis library to interact with Alfresco. To query documents there is a method called queryObjects, which takes in an OperationContext as an argument. On this context, I can set a boolean flag, called setLoadSecondaryTypeProperties. However, even if I set it to true, it won't return the secondary type properties. I can only reach those properties if i use a SELECT query and join the two "tables" together on cmisbjectId.

The problem is, that the select query doesn't return cmis Document types, it returns QueryResult types, and it can't be casted, and I really need the Document.

Am I missing something here?

Thanks in advance!

Bence

You can try

operationContext.setFilter(null);

It means select all properties from query type

Sadly, it doesn't seem to work

Could you paste your code here ?

what params did you pass to

 queryObjects(String typeId, String where, boolean searchAllVersions,
            OperationContext context);

Have you tried to pass typeId your specified type instead of cmis:document/cmis:folder?

BenceKovacs

Yes, we have a custom type derived from cmis:document, lets call it invoiceScan

final OperationContext ctx = OperationContextUtils.createMaximumOperationContext();
		ctx.setLoadSecondaryTypeProperties(true);
		ctx.setFilter(null);
		
		final ItemIterable<CmisObject> result = session.queryObjects(
				"invoiceScan",
				"cmis:name = 'testName'",
				false,
				ctx);

This way i get back the desired document and all the properties from our specified custom type, i can see the "SecondaryTypeIds" property too, but i dont't get the properties OF the secondary type.

I've tried creating the minimum operation context, the maximum, the default from the OperationContextUtils aswell.

Now i use cmis:name in the where clause, but I'll want to use secondary type properties there if i somehow manage to get them.
