You're not using a model for your label - so you are "pushing" data into it
on creation and never changing the data after it's initially created. This
is easily learned / proven if you put a breakpoint there where you are
creating your label.
Actually, now that I look at it, you're also not using a model for your
columns in your toolbar. I'm not sure what your AbstractReportingBean is,
but you will probably also need to change your RepeatingView to something
that takes an IModel<List> and creates the columns on the fly - or else
you'll get old data.
Here's an example for the Label - but you'll have to do the repeater on your
own.
total.add(new Label("value", new AbstractReadOnlyModel<String>() {
String getObject() {
String val = row.getStringForFieldNamed(column.getSortProperty());;
return StringUtils.isEmpty(val) ? "nbsp;" : val;
}
});
