Hi:
I have a simple test application that, with my data, is putting the Vaadin table loader into a loop. The RowCount at the top of the table shows 229 rows, but the table only displays 21 of them. When I put the Vaadin debugger on, I see messages going back and forth between the client and the server at a high rate, and they seem to be requesting the same group of rows over and over again.
I have attached the application, but I don’t know how to give you the database rows so you can see what I see? Here is a screenshot:
As you can see, the table is only partially loaded. If I scroll way down (to where I expect the 229th row would be), I see the buttons.
Running with Vaadin debug, I see these messages over and over:

Need an expert for this one. Thanks in advance.
