> Key: XMLBEANS-351
> URL: https://issues.apache.org/jira/browse/XMLBEANS-351
> Project: XMLBeans
> Issue Type: Bug
> Components: XmlObject
> Affects Versions: unspecified
> Environment: XmlBeans
> Reporter: Michael Hedenus
> Fix For: unspecified
> 
> 
> Currently there is no public interface to check if an XmlObject is orphaned; there \
> is only a protected method in XmlObjectBase. Consider following situation: 1) The \
> XmlBeans data model is display by a GUI (e.g. JTree). 2) The data model is changed, \
> e.g. an element is deleted. 3) The GUI is repainting but the element that shall be \
> displayed is orphaned and an exception is thrown. This exception must be caught to \
> keep the GUI in a valid state or even alive. The last point is the reason why I \
> consider the problem as a bug. Of course it is always possible to surround the \
> accessing of XmlBeans with try-catch but I think this is neither the intention nor \
> a good solution. I propose two possible solutions:
> 1) instance method for XmlObject: isOrphaned()
> 2) static utility function: XmlBeans.isOrphaned(XmlObject)
