This is a variant on the problems described in that post.
I have a h:selectOneMenu with as value 'bean.organisation'.
The problem is, that for each element rendered using s:selectItems, the expression for the value of h:selectOneMenu is evaluated. The bean is in conversation scope and this results in a lot of unneeded in/out-jection.
I can work around this by putting the currently selected value directly in conversation scope, or in another class that I outject.
But is there an easier way to have the expression for current value only evaluated once?
