I have a CheckGroup like this 

CheckGroup  grp= new CheckGroup ("group", new ArrayList());

And I am addding a  CheckGroupSelector to this.

grp.add( new CheckGroupSelector("selectall"));

Using dataview and bean i am adding CheckBox to the grp.

What my purpose  is i want to select all check box from CheckGroupSelector
and then onsubmit all data should be deleted from the database and updated
list of should render.

If i check CheckGroupSelector and wait for few second and then submit the
form i get expected result.

But If i check CheckGroupSelector and without waiting click submit button i
get an exception.


i there any way to put a sleep after clicking CheckGroupSelector  and before
