Bug with Back button in CheckBoxList

Hi,

There is a bug in the control CheckBoxList:

the number of Items checked is not correct after a Back in browser:

Steps to repro:

Create a Page-> add CheckBoxList control -> Add 3 items -> run it

....

Select Item 1 -> submit

Select Item 2 -> submit

Press button back

Items 1+2 are checked but internally in debug mode,

....

If you add a javascript client to handle each click to individual checkbox, in debug mode,

this is weird to see that item #2 is not checked but just after readystate = complete, the same item #2 is checked. !!!?????

Any ideas to workaround this ?

Thanks
