This is the reasons I sometimes have an action in my "input" action
attribute. What I mean is:
<action path="/showForm.do"
type="com.actions.ShowFormAction">
<forward name="form" path="myForm.jsp"/>
</action>
<action path="/submitForm.do"
type="com.actions.SubmitFormAction"
name="myFormBean"
input="/showForm.do">
...
</action>
I sometimes (often?) use the Action that generated the form as my input
because my form has controls that need to be initialized (like your drop
downs).
Using an Action as "input" sometimes takes more work. Your action should
know that it's only redisplaying a form and not reset all form values (or
else the user will have to reinput everything instead of just correct the
validation error).
You *can* avoid this by placing your list in session scope, like Mike
suggested. If it's used often enough, you can put it in application scope,
though you'd have to define when "often enough" is justified.
Try the session scope approach first.
