[dna-issues] [JBoss JIRA] Commented: (DNA-341) Graph API behavior when removing all property values doesn't reflect that of JCR

Graph API behavior when removing all property values doesn't reflect that of JCR -------------------------------------------------------------------------------- Key: DNA-341 URL: https://jira.jboss.org/jira/browse/DNA-341 Project: DNA Issue Type: Bug Components: API, Graph, JCR Affects Versions: 0.3 Reporter: Randall Hauch Assignee: Randall Hauch Priority: Critical Fix For: 0.4 Attachments: DNA-341.patch Section 4.7.3 of the JSR-170 specification (version 1.0.1) states: Every property must have a value. The range of property states does not include having a "null value", or "no value". Setting a property to "null" is equivalent to removing that property. In the case of multi-value properties, the setting of a particular value within the array to null results in the removal of that value and the compacting of the array. As a result it is possible to have a multi- value property with no values (an empty array). See 7.1.5 Adding and Writing Properties. However, currently the Graph API and connector behavior is such that whenever a property is updated (or set) to no values, the property is removed automatically. This means that it is not possible for the Graph API or connectors to support a multi-valued JCR property with no values.
