i tried select component but i have difficulty and got stuck on it.
i had already read the archive milis, but still have no idea what had
happened with mine
here's my code....
i always get null value(no data) to diplay in my select component.
when i debug it,
getPositionList() in Home.java always return a list of value.
but it doesn't work when i try to call the model : return new
PositionSelectionModel(getPositionList());
does anyone can help clear me up....
thnx...
