I seem to be having this same issue. Where you able to resolve the problem? If so could you be so kind as to explain how?

[Chris Kühl，修改在11 年前。]

Seems I'd forgotten to change the null being returned from the getClassNames method that was generated by Eclipse. Now that I'm returning the class names it works.

I have had the same problems before but most of the times it's related to corrupt xml , try and check with some wrong white spaces, line breaks.If it's still there give the complete stack trace here

[Laura Liparulo，修改在11 年前。]

I got the same error and I've solved it. in my case it was a bug in the portlet action class, where i was taking a parameter declared as a global variable.
If you invoke it within the metod the "null portlet bag" error is fixed. if you declare and inizialize "archivePath" as a global class variable you get the null portlet bag error.
The right way is this:

public void refreshDatabase(ActionRequest actionRequest,
ActionResponse response) throws Exception {

String archivePath = getInitParameter("archive-folder");
logger.info("Refresh Database clicked");
try {
DBUtil.refreshDatabase(archivePath);
SessionMessages.add(actionRequest, "success-db");
SessionMessages.add(actionRequest, "tables-up");
} catch (Exception e) {
SessionErrors.add(actionRequest, "error-db");
}
}

I hope it helps :-)
