<h3><a name="problems">Known issues</a></h3>
<p>There are some limitations of the 1.0 release relating to parser support,
which will be removed in the 1.1 release. First off, the <a
href="http://www.xmlpull.org">XMLPull</a> parser used by 1.0 does not support
some features of XML, including DTDs and entities. This is generally not an
issue for data-oriented XML exchange, but might be a concern for some users with
specialized requirements. For example, entities are often used in
document-oriented XML to break up a complex document into pieces which can then
be included into a single composite document. The XMLPull parser also does not
support schema validation. The JiBX 1.1 release will support using StAX parsers
as an alternative to XMLPull, allowing users for whom full XML support is
important to select a parser which implements all required features.</p>
<p>Aside from that, there's a known inconsistency in the way certain
combinations of optional components are handled. This is not really a bug, but
rather an ambiguity in the way optional items are interpreted. It's likely to
remain until JiBX 2.0:</p>
<ul>
<li>Optional structures are not handled consistently unless they have an associated
property value. In other words, structures that just define a wrapper element
around some content that's part of a containing object won't always work as
expected if you make them optional. This creates problems in trying to wrap
text or CDATA values with elements to make them optional using binding constructs like:
<div id="source"><pre><structure name="wrapper" usage="optional">
<value style="cdata" field="m_rawText" usage="optional"/>
</structure></pre></div>
The result is that if the <b>m_rawText</b> field is <code>null</code> an empty
<b><wrapper></b> element will be generated when marshalling, which will then
be converted to an empty string value when unmarshalling. There is a work-around
for this, which is to use a <b>test-method</b> on the <b>structure</b>. The test
method can check if the field value is null, and if so return false.</li>
</ul>
<p>This list will be updated on the web site if major new issues are found, but
please check the issue tracking system (described below) for the latest problem
information.</p>
</div>
<div class="h3">
<h3><a name="reporting">Reporting Problems</a></h3>
<p>If you run into problems with the code please check existing bug reports for
information on fixes, and enter a new bug report if you don't find one matching
your problem. JiBX uses the <a
href="http://jira.codehaus.org/secure/BrowseProject.jspa?id=10410">Jira issue
tracking system</a> hosted by <a href="http://www.codehaus.org/">The
Codehaus</a>. Please note that JiBX is not otherwise affiliated with The
Codehaus, and other aspects of the project remain hosted on <a href="http://sf.net">
SourceForge</a>. You can browse the Jira bug list without restriction, but will
need to register in order to enter new issues.</p>
<p>You can help make sure your problem is addressed quickly and completely by
attaching sample code to demonstrate the problem. The sample code should be
packaged as a <i>zip</i> or <i>tar.gz</i> file, and should
include an Ant <i>build.xml</i> script to compile the code, run the binding
compiler, and (for runtime problems) execute a test of the binding. The
<i>starter</i> example included in the JiBX distribution shows how this can
work.</p>
<p>For general help on using JiBX you can check the <a href="faq.html">FAQ</a>, the new <a
href="http://wiki.jibx.org">Wiki</a>, and the <a href="mail-lists.html">mailing
lists</a>.</p>
