I hope that someone can answer this simple question.
If I have object Person buyer; in my Fruit class (with
get/set methods), and I have fruit object in my action class,
where I also have List<Person>allBuyers in my action class. How can I
define combo box so that when buyer is selected, that Person object
should be set to my fruit.buyer object ?
When I set my combo box like this:
<s:select id="buyer" label="Buyer"
list="allBuyers" name="fruit.buyer" emptyOption="false"
listKey = "id" listValue = "name"
headerKey="None" multiple="false"/>
but in this case it don't set my fruit.buyer to one choosed in combo box, and I
get an error:
18:42:32,812 ERROR
com.opensymphony.xwork2.interceptor.ParametersInterceptor:204 -
ParametersInterceptor - [setParameters]: Unexpected Exception caught setting
'fruit.buyer' on 'class com.myproject.actions.FruitBuyerAction: Error setting
expression 'fruit.buyer' with value '[Ljava.lang.String;@8825a5'

Now I have the same
problem with my datetimepicker field. I have "date" attrib (of type
java.util.Date with get/set methods) in my Fruit class. I have defined
it in jsp like this:
displayFormat="dd.MM.yyyy" label="Date" type="date"/>

One more thing, if I have object Person buyer; in my Fruit class (with
get/set methods), and I have Fruit fruit object in my action class,
where I also have List
allBuyers in my action class. How can I
define combo box so that when buyer is selected, that Person object should

When I removed listKey then it works good. But I now have the same
problem with my datetimepicker field. I have "date" attrib (of type
java.util.Date with get/set methods) in my Fruit class. I have defined it in
jsp like this:
displayFormat="dd.MM.yyyy" label="Date" type="date"/>

Ok.. if i get your idea... the list yout want to put in combobox is
fruit.buyers, hummmm?
Then, try it:
listKey="personId" name="fruit.buyers" emtpyOption="false"
hedaerKey="none"/>
if you have the object fruit, then:
listValue="personName" listKey="personId" name="fruit.buyers"
emtpyOption="false" hedaerKey="none"/>
maybe the name is not correct. Try chage the attr name to person, for
example.
listValue="personName" listKey="personId" name="person" emtpyOption="false"
hedaerKey="none"/>
