Description

A MV property with 1 empty string value is serialized as "[]". When deserialized, this results in an empty MV property with 0 values.

eg:

<?xml version="1.0" encoding="UTF-8"?>
<jcr:root xmlns:sling="http://sling.apache.org/jcr/sling/1.0" xmlns:jcr="http://www.jcp.org/jcr/1.0"
jcr:primaryType="sling:Folder"
allowedChildren="[]"/>

This is a flaw in the DocViewPropertyFormat. the simplest solution is to mark an empty string value with \0.
eg:

allowedChildren="[\0]"
