For some reason the exception is not being output to the log or console. I
have the log level in log4j setup as debug but nothing is recorded....weird.
I am trying to upload an image to nabble of the intellij debugger showing
the error. This occurs as I step over the code
ListView procedures = new ListView("procedures", resultsList) {
protected void populateItem(ListItem item) {
List procedure = (List) item.getModelObject();
item.add(new Label("equipment", (String) procedure.get(0)));
}
};
