vaadin 6.3.0 version - table problem

I downloaded the latest 6.3.0 and installed it.

There is a problem :

I have master detail form (in split forms).
I have a table showing rows and when I click on it, it shows the details in the form (all fields).
It is split form.

There is sort icon in the header of columns, so I can sort on every field on table and when I click it , it sorts the table column.

Now the problem is - after I sort and then click on one of row the details are not showing up in the form !!

But if I do not sort and click on row then the details are shown in the form in split container.

Before 6.3.0 - it worked fine in 6.2.x no problem.
Something is broken in 6.3.0

It's a problem with sorting a BeanItemContainer and has been fixed already. Test a nightly build of 6.3 or wait for 6.3.1 to be released in a few weeks
