             Project: Roller
          Issue Type: Bug
          Components: Import / Export
    Affects Versions: 5.0
            Reporter: Greg Huber
            Assignee: Roller Unassigned


Hello,

When uploading a file,  FileManager.canSave() uses 
errors.addError("error.upload.badPath").  In Resources #253 there is a check 
for any errors:

for (Iterator it = errors.getErrors(); it.hasNext();) {
            RollerMessage msg = (RollerMessage)it.next();
            addError(msg.getKey(), Arrays.asList(msg.getArgs()));
}

 but msg.getArgs() would be null,  as errors.addError("error.upload.badPath") 
needs to be errors.addError("error.upload.badPath","SomeText").

need:

for (Iterator it = errors.getErrors(); it.hasNext();) {
            RollerMessage msg = (RollerMessage)it.next();
            if (msg.getArgs() != null) {
               addError(msg.getKey(), Arrays.asList(msg.getArgs()));
            } else {
               addError(msg.getKey());
            }
}

 also error.upload.badPath needs to be added the 
ApplicationResources.properties.

Cheers Greg
