Dropdown box value reset upon partial submit

[Subash Karuppiah]

Hi, I had been in the process of changing List boxes in a application into dropdown combobox. It happened like this that i introduced a new combo box to filter the username( that is first one is customer list, second user list based upon customer. Third is software and last is version list based upon software). The thing is that my first and third combo box are "partial submit", so what happens is the selected value in second combo box is getting reset upon the "partial submit" of the third value. What should i do!? Is there a way to group the list box such that each others action does not affect the other!! Thanks!!
