Alexander Pinske commented on XMLBEANS-579:
-------------------------------------------
Yes, I did that. But the call to createSampleForType is private. So I need to
call it using reflection. It works tho.
{code:java}
public static String createSampleForType(SchemaGlobalElement element)
throws NoSuchMethodException, IllegalAccessException,
InvocationTargetException, InstantiationException {
SchemaType sType = element.getType();
XmlObject object = XmlObject.Factory.newInstance();
XmlCursor cursor = object.newCursor();
// Skip the document node
cursor.toNextToken();
// Using the type and the cursor, call the utility method to
get a
// sample XML payload for that Schema element
Constructor<SampleXmlUtil> sampleXmlUtilCtor =
SampleXmlUtil.class.getDeclaredConstructor(boolean.class);
sampleXmlUtilCtor.setAccessible(true);
Method createSampleForTypeMethod =
SampleXmlUtil.class.getDeclaredMethod("createSampleForType", SchemaType.class,
XmlCursor.class);
createSampleForTypeMethod.setAccessible(true);
createSampleForTypeMethod.invoke(sampleXmlUtilCtor.newInstance(false), sType,
cursor);
// Cursor now contains the sample payload
// Pretty print the result. Note that the cursor is positioned
at the
// end of the doc so we use the original xml object that the
cursor was
// created upon to do the xmlText() against.
XmlOptions options = new XmlOptions();
options.setSavePrettyPrint();
options.setSavePrettyPrintIndent(2);
options.setSaveAggressiveNamespaces();
options.setSaveSyntheticDocumentElement(element.getName());
return object.xmlText(options);
}

> SampleXmlUtil misses root element with only one child

> Project: XMLBeans
> Issue Type: Bug
> Affects Versions: Version 5.0.1
> Reporter: Alexander Pinske
> Priority: Major
>
> When generating a sample, usually the top-level-element is xml-fragment. But
> when the type contains only one child-element, it becomes the root.
