Hi, Use a ListView.
The model of the second form is not updated until the form is submitted. You need to perform a submit if you want to see this model updated, and the correct value for tst.getCheckedTestBeans().size(). If you want to avoid the manual submit phase, you need to use Ajax. Please find here your code slightly modified.
