bufferview refresh problem

[Fabrice]

I have a datagrid with about 1000 rows, i use bufferview and rowStyler to fill the datagrid with method 'loadData' and i notice that at the first call, datagrid stay empty but 'getData' tell me that there are 1000 rows.
if bufferview.js if i change one parameter in function init() of OnBeforeRender() method, this problem disapear :

Code:

view.scrollTimer = setTimeout(function(){
						scrolling.call(view);
					}, 600);

I set 600ms in place of 50ms, can you explain me why it does'nt work with 50ms?
