XPath on a copy() of an XMLBeans comp derived class fails
----------------------------------------------------------
Key: XMLBEANS-409
URL: https://issues.apache.org/jira/browse/XMLBEANS-409
Project: XMLBeans
Issue Type: Bug
Components: Cursor, DOM, XmlObject, XPath
Affects Versions: Version 2.4
Environment: Windows XP Professional
JDK 1.6.0_07
Saxon 9.0.0.4
XMLBeans 2.4.0
Reporter: Bryan Worrell
I can execute an XPath on an XMLBeans derived class using selectPath(...) and
it will behave as expected; returning 0-n results in an XmlObject[] array.
However, if I create a copy of the object and execute an XPath on it, every
XPath will return a zero-length array.
The examples behave properly with XMLBeans 2.3.0 with Saxon 8.8. I noticed
this issue when I switched to XMLBeans 2.4.0 and Saxon 9.0.0.4. The issue
remains if I use XMLBeans 2.4.0 and Saxon 9.1.0.6 (the current release at the
time of this posting).
So, given this example:
<AppDoc>
<Applications>
<ApplicationType>
<Name>foobar</Name>
</ApplicationType>
<Applications>
</AppDoc>
/**
Say we pass in the ApplicationType object with the Name of "foobar"
**/
public void confuseTheDeveloper( ApplicationType app ){
String xPath = "$this/*:Name";
ApplicationType appCopy = (ApplicationType)app.copy();
XmlObject[] objs = app.selectPath( xPath );
XmlObject[] otherObjs = appCopy.selectPath( xPath );
System.out.prinln( objs.length > 0 ); // prints 'true' ... like it should
System.out.println( otherObjs.length > 0 ); // prints 'false' ...even
though it should print 'true'
}
/**
Another example
**/
public void moreConfusion(){
ApplicationType app = ApplicationType.Factory.newInstance();
app.setName( "foobar" );
XmlObject[] objs = app.selectPath( "$this/*:Name" );
System.out.println( objs.length > 0 ); // prints false
}
