[jira] [Commented] (CMIS-686) Cannot execute query via Drupal CMIS API client

["Florian Müller (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CMIS-686?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13700139#comment-13700139 ] 

Florian Müller commented on CMIS-686:
-------------------------------------

I can't see why these are OpenCMIS issues.

1) Wrapping the query in a CDATA section is not specified by CMIS. Why should OpenCMIS support it then?

2) Optional parameters must either have a value or the tags shouldn't be there. For example, includeAllowableActions is boolean value. Either it is "true" or "false" or not existent. includeAllowableActions with an empty value is not defined by the spec.

These are Drupal CMIS issues, not OpenCMIS issues.

> 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}
