[dna-issues] [JBoss JIRA] Commented: (DNA-304) SessionCache Uses Graph Layer Cardinality for Properties Instead of Cardinality from JCR Property Definition

[Randall Hauch (JIRA)]

    [ https://jira.jboss.org/jira/browse/DNA-304?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12457682#action_12457682 ] 

Randall Hauch commented on DNA-304:
-----------------------------------

Applied the patch the corrected SessionCache to determine the multiplicity using the property definition rather than the number of values in the DNA property.  All current tests pass.

> At the graph layer, property cardinality (whether the property is single- or multi-valued) is determined based on the values set on the property (i.e., any property with only one value is single-valued, any property with more than one value is multi-valued).   At the JCR layer, property cardinality is supposed to be based on the property definition in use for the property.  
> The SessionCache is currently basing the JCR layer cardinality on the graph layer cardinality instead of the JCR property definition.  
> Example:
> Consider a node that has one value for jcr:mixinTypes.  At the graph layer, this property will be single-valued.  At the JCR layer, this property should be multi-valued based on the jcr:mixinTypes property definition from the nt:base type (which is inherited by all nodes).
