source bean and target bean
the target bean is DataPanel, the source bean is Row. DataPanel has an
unknown quantity of Row instances (I'd be happy with one).
At over 200 lines, certainly the code can't be called "short". In any
event, what I'd like is to add the rows in List<Row> onto the JavaBean
DataPanel, which is then added to AppFrame.java.
The number of rows, and what to set them to, is discovered at runtime
from the database and seems to be working fine, at least according the
System.out statements within the javabeans.
Is the Row being added to the DataPanel? I have only the visual evidence
which says "no". I don't think it's a matter of updating the GUI,
somehow it's not making it into the GUI.
