<s:select label="Pets"
name="petIds"
list="petDao.pets"
listKey="id"
listValue="name"
multiple="true"
size="3"
required="true"
value="%{petDao.pets.{id}}"
/>
<s:select label="Months"
name="months"
headerKey="-1" headerValue="Select Month"
list="#{'01':'Jan', '02':'Feb', [...]}"
value="selectedMonth"
required="true"
/>
// The month id (01, 02, ...) returned by the getSelectedMonth() call
// against the stack will be auto-selected
MG>so in first case execute() would call the value getId()
MG>in the second case value is selectedMonth so execute() would call
getSelectedMonth()
Note: For any of the tags that use lists (select probably being the most
ubiquitous), which uses the OGNL list
notation (see the "months" example above), it should be noted that the map key
created (in the months example,
the '01', '02', etc.) is typed.
'1' is a char,
'01' is a String,
"1" is a String.
This is important since if
the value returned by your "value" attribute is NOT the same type as the key
in the "list" attribute, they
WILL NOT MATCH, even though their String values may be equivalent. If they
don't match, nothing in your list
will be auto-selected.
