> Using the Query module of version 7.x-1.3 of the Drupal CMIS API client, a query fails
against a server built using OpenCMIS 0.9.0.
> This is down to two issues:
> 1) The Drupal CMIS API client now wraps the query in a CDATA section in the XML that's
POSTed to the server. The XMLUtils.readText method does not handle the XMLStreamReader.CDATA
event; as a result, an empty statement string is returned.
> 2) The Drupal CMIS API client can also send empty XML elements for the options searchAllVersions,
includeAllowableActions, etc. Unfortunately the XML parser interprets these as empty strings
(rather than null values). The various read... methods in XMLWalker (readBoolean, readInteger,
readDecimal, readDateTime) should return a null value if the text is interpreted as an empty
string; for example:
> {code}
> protected Boolean readBoolean(final XMLStreamReader parser) throws XMLStreamException
{
>     String value = readText(parser);
>     if (value == null || "".equals(value)) {
>         return null;
>     }
>     ...
> {code}
