NPE in XWorkConverter.loadConversionProperties after adding DateConverter
-------------------------------------------------------------------------
Key: WW-1978
URL: https://issues.apache.org/struts/browse/WW-1978
Project: Struts 2
Issue Type: Bug
Components: Actions
Affects Versions: 2.0.8, 2.0.6
Reporter: Matt Raible
I recently added a DateConverter to my project (Struts 2.0.6, Maven 2) and now
I'm getting NPEs when running tests.
xwork-conversion.properties:
java.util.Date=org.appfuse.webapp.action.DateConverter
DateConverter.java:
public class DateConverter extends StrutsTypeConverter {
public Object convertFromString(Map ctx, String[] value, Class arg2) {
if (value[0] == null || value[0].trim().equals("")) {
return null;
}
try {
return DateUtil.convertStringToDate(value[0]);
} catch (ParseException pe) {
pe.printStackTrace();
throw new TypeConversionException(pe.getMessage());
}
}
public String convertToString(Map ctx, Object data) {
return DateUtil.convertDateToString((Date) data);
}
}
My test's setUp() method:
@Override
protected void onSetUpBeforeTransaction() throws Exception {
LocalizedTextUtil.addDefaultResourceBundle(Constants.BUNDLE_KEY);
ActionContext.getContext().setSession(new HashMap());
// change the port on the mailSender so it doesn't conflict with an
// existing SMTP server on localhost
JavaMailSenderImpl mailSender = (JavaMailSenderImpl)
applicationContext.getBean("mailSender");
mailSender.setPort(2525);
mailSender.setHost("localhost");
// populate the request so getRequest().getSession() doesn't fail in
BaseAction.java
ServletActionContext.setRequest(new MockHttpServletRequest());
}

I tested this with Struts 2.0.8 and there's no change.
I posted this to the mailing list, but received no responses.
