struts select example
<s:select label="Pets"
name="petIds"
list="petDao.pets"
listKey="id"
listValue="name"
multiple="true"
size="3"
required="true"
value="%{petDao.pets.{id}}"
/>
list:
Iterable
source to populate from. If the list is a Map (key, value),
the Map key
will become the option 'value' parameter
the Map value will become
the option body.
listKey:
Property of list objects to get field value from
value:
Preset the value of input element.
toString displays
yadda.yadda.payper...@dfg65
which is the generated byte code for the entire map
sub in classname for PetDao
yourMap name for pets
and you should see the value come back
