s:radio and s:checkboxlist - how to customize listValue property.
When I use that 2 components in my form I need to set attributes listValue
and listKey.
That attributes as I understand require a field of a bean that is a member
of collection represented by list attribute.
Example:
<s:radio list="types" name="type" label="Type" listValue="name"
listKey="id" />
That means:
1) there will be one radiobutton for each element of collection getTypes().
2) Each html radiobutton will have value = getId() and label = getName() .
I want to compose label from several fields of my bean. So I can't write
<s:radio listValue="someField" />
because that class doesn't have getSomeField() method.
How can I do this ?

Unfortunately it is the case, so I need another solution.

The easiest (I'm not going to say "best") solution is to make a "fake"
getter on your bean. Make a "getListLabel()" method that composes a String
from the values that you want to display in the list label, and then set the
listValue to be "listLabel". This is the way I've done this in the past and
it works OK. It isn't ideal if you want to keep your model carefully
isolated from your UI but my own designs are a little less pure than that.
