[jira] Commented: (JCR-981) XPath pseudo property support missing for "is null" and "is not null"

["Julian Reschke (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/JCR-981?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12508208 ] 

Julian Reschke commented on JCR-981:
------------------------------------

Seems to be caused by missing code in 

  XPathQueryBuilder.visit(SimpleNode, Object)

for case JJSTEPEXPR when isAttributeAxis returns false, and queryNode.getType() is OPERATION_NULL or OPERATION_NOT_NULL.
