Subject [jira] [Commented] (SLING-7218) NPE in org.apache.sling.security.impl.ContentDispositionFilter#activate
Date Tue, 31 Oct 2017 13:30:01 GMT

    [ https://issues.apache.org/jira/browse/SLING-7218?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16226783#comment-16226783
] 

Konrad Windszus commented on SLING-7218:
----------------------------------------

This is correct. According to DS 1.3 an array property which is not set defaults to null (irrespective
of the configuration property fields default value which is only evaluated at build time).
This is also described in https://osgi.org/bugzilla/show_bug.cgi?id=208. I would suggest to
accept {{null}} here.
