How to associate more than one relation to a content instance

Hi,

I don't know why this is causing me so much trouble. I have a relator on a content instance that allows static files to be associated. I'm able to create the static file and commit it. But, when I try to create a relation instance and associate it, WEM is throwing an exception. Here is the relevant piece of code:

ContentRelationInstance contentModuleRelationInstance = new ContentRelationInstance();
contentModuleRelationInstance.setObjectTypeRef(StaticFile.getTypeObjectTypeRef());
contentModuleRelationInstance.setAttributeValue("RELATOR-ID-ATTRIBUTE", sf.getContentManagementId());

AttributedObject[] relations = {contentModuleRelationInstance};
ci.setRelations("RELATOR-MAPPING", relations);
ci.commit();

It throws this exception:

This is because you are setting the file StaticFile object type ref. The content relation instance belongs to your content type so you should set the ref of such a content type....

Hi,

AttributedObject[] relations = {contentModuleRelationInstance};
ci.setRelations("RELATOR-MAPPING", relations);
ci.commit();

Mario,

Thanks for the reply.

So, it should be the content type of the "primary" content type you are creating? For example, if your content type is 'Foo' that contains the relator, would you use the Foo content type? Other than that, I'm not sure what content type to use since the item attached to the relator is a Static File.

Thanks,

Eric

Mario_DAnna

Correct.

Let us say you want to add a relation to a ci

ContentInstance ci = ... ;

Then use

ContentTypeRef ctRef = (ContentTypeRef)ci.getObjectTypeRef();

ciao

Mario

Mario,

So, I understand what you're saying. In your version, the ContentRelationInstance will have the content type reference to the item that is the target of the relation. Like this:

Content Instance #1 -> relator -> Content Instance #2 -> Static File

But, in our case, we do not have a Content Instance #2. We are trying to do this:

Content Instance #1 -> relator -> Static File

And, we are simply trying to do this:

ContentInstance ci = (ContentInstance) ContentInstance.findByContentManagementId(new ManagedObjectVCMRef("<Content Instance #1>"));
StaticFile sf = (StaticFile) StaticFile.findByContentManagementId(new ManagedObjectVCMRef("<Static File>"));
ContentRelationInstance cmri = new ContentRelationInstance();
cmri.setAttributeValue("STATIC_FILE_ID", sf.getContentManagementId());
AttributedObject[] relations = {cmri};
ci.setRelations("RELATION-ID-NAME", relations);
ci.commit();

So, what should we use for the Content Type of the relation in that case?

Thanks,

Eric

Mario_DAnna

Eric, this is how the code should be

ContentInstance ci = (ContentInstance) ContentInstance.findByContentManagementId(new ManagedObjectVCMRef("<Content Instance #1>"));

StaticFile sf = (StaticFile) StaticFile.findByContentManagementId(new ManagedObjectVCMRef("<Static File>"));

ContentRelationInstance cmri = new ContentRelationInstance(ci.getObjectTypeRef());

cmri.setAttributeValue("STATIC_FILE_ID", sf.getContentManagementId());

AttributedObject[] relations = {cmri};

ci.setRelations("RELATION-ID-NAME", relations);

ci.commit();
