[jira] Created: (WSCOMMONS-348) A single instance of OMDOMFactory
can't be used to create multiple documents
A single instance of OMDOMFactory can't be used to create multiple documents
----------------------------------------------------------------------------
Key: WSCOMMONS-348
URL: https://issues.apache.org/jira/browse/WSCOMMONS-348
Project: WS-Commons
Issue Type: Bug
Components: AXIOM
Reporter: Andreas Veithen
OMDOMFactory contains the following code:
protected DocumentImpl document;
public OMDocument createOMDocument() {
if (this.document == null)
this.document = new DocumentImpl(this);
return this.document;
}
This means that when createOMDocument is invoked several times on the same OMDOMFactory instance, the same OMDocument object is returned, i.e. a single instance of OMDOMFactory can't be used to create multiple documents. This is OK if DOOMAbstractFactory was used to obtain the OMDOMFactory because it creates a new instance each time. However OMAbstractFactory considers the factories as singletons and therefore configuring OMDOMFactory as the default OMFactory leads to unexpected results.

[jira] Resolved: (WSCOMMONS-348) A single instance of OMDOMFactory
can't be used to create multiple documents
Posted by "Andreas Veithen (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/WSCOMMONS-348?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Andreas Veithen resolved WSCOMMONS-348.
---------------------------------------
Resolution: Won't Fix
This issue is not fixable (at least not easily) due to the fact that DOM requires nodes to have an owner document even if they have not yet been added to a tree. I updated the Javadoc of OMAbstractFactory and OMDOMFactory to explain this and to specify the restrictions that apply to the usage of OMDOMFactory.
