deleteContentRelations

Rhythmyx Technical Discussion
1

I have been struggling for more than a day now with this null pointer exception. I have confirmed multiple times that the guid list is not null, and the guids being supplied are valid.

Whenever I invoke deleteContentRelations(sortedListOfGuids), I get the following exception. I have verified that sortedListOfGuids is not NULL and it does have some valid Guids in it.

What about a user name? Did you verify that was being sent with your request?

Per Javadocs, the API for this method only takes one parameter which is a list of GUIDs.
void deleteContentRelations(List<IPSGuid> ids)

The version that takes the user, says it is deprecated.
Moreover, this method is being invoked from within a preprocessor extension.

Also I dont understand how does this method works. It only takes the list of GUIDs of the content items. The same content item can possibly be added to one or more slots. Since it doesnot takes the slot name or the parent GUID, how does it knows from which slot to delete the content item relation.

This method wants the GUID of the relationship, not the GUID of the item.

you have get the relationships (with loadContentRelations), then build a list of GUIDs by calling the getGUID() method on each relationship.
