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
            Priority: Critical
             Fix For: 0.4


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.
