             Summary: The XML object store cannot handle all "char" values
                 Key: ISIS-269
                 URL: https://issues.apache.org/jira/browse/ISIS-269
             Project: Isis
          Issue Type: Bug
          Components: Core: MetaModel, Runtimes: Dflt: Objectstores: XML
    Affects Versions: 0.2.0-incubating
            Reporter: Kevin Meyer
            Priority: Minor


The XML object store relies on "facet.toEncodedString(associatedObject)" to return an XML compatible representation of the property value.
For "char", this encoded string is the raw character.
Which for values < 32, kills the XML decoder with "invalid unicode character .." exceptions.
e.g. for character value (char) (20):
The exception is:
[Fatal Error] :6:31: An invalid XML character (Unicode: 0x14) was found in the element content of the document.

The XML file contains:
  <value field="charProperty">|</value>
(The actual character did not survive "copy&paste")



If I use (char) 255:
The XML file contains:
  <value field="charProperty">ÿ</value>

Whether this is a problem with the char encoder or XML, is perhaps up for debate.
