Rowcount is zero , but the table displays data on the screen

Question

Hi,
I have created an arraylist, which holds objects of a custom class. The custom class contains variables, that holds the data of each row.
I did binding between this arraylist and a table. On the UI, the table is displayed with the data present in the class variables.
But, when I use getrowCount(), it returns zero.
Probably because of this reason, the selected row data is null. (tableselectone component).
Any help is appreciated.
