I have a hashMap<string,Set<postcode>>codeMap in action to receive a group of
textfields values. Each map's value mapping with a struts textfield.
my convertFromString fuction work well, all textfield could be converted to
a Set<postcode>.
but when i want to convert the map back to textfield in result.jsp
<s:iterator value="codeMap">
<s:textfield value="%{value}><s:textfield>
</s:iterator>
the convertToString work but the parameter object is NULL!!!!!!!!!
if I change the struts tag to:
<s:iterator value="codeMap">
<s:property/>
</s:iterator>
the convertToString function work well and the result page could display
what I inputed in textfields
any know why struts can not forward map's value to convertToString? many
thanks
