s:select and non-primitive values 2007-01-29 - By Laurie Harper

I suspect this may be related to the recently mentioned bug/limitation
in s:select, but I haven't been able to figure out how to work around it
if so. I'm trying to create a select input for a model property which
has a POJO type (actually, a persistent entity). Here's a rough outline:
public class Region {
public Integer getId() {...}
public String getName() {...}
}
public class Player {
public Region getRegion() {...}
public void setRegion(Region region) {...}
}
public class SomeAction {
public Object getModel() {/*returns Player*/}
public List<Region> getRegions() {...}
}
<s:select name="region" list="regions"
listKey="id" listValue="name"
headerKey="-1" headerValue=""
label="Region:" labelposition="left"/>
This works well except for selection of the current value. The select
input always shows with the default/empty option selected. Making
Region.getId() return 'int' instead of Integer doesn't seem to help, and
I'm not able to find any other combination of changes that does work.
I should point out that I also have a converter registered globally for
the Region type. It only ever gets called on form submission, though, to
convert the selected value from String id to a Region instance. It's
never called to convert from Region to String.
Am I doing something fundamentally wrong? The selected value *is* set on
the Player model instance, so everything seems to be working fine except
for the display of the current property value in the form.
