Gets the key from the map entry and displays it; OK here.
> fruits Val <s:text name="%{fruitsStat.value}" />
Gets the 'value' property of the iterator status object and uses that as
a lookup key in the application's message resources. Umm... First, I'm
not sure if the iterator status object has a value property, but
wouldn't you want the value from the map entry? And second, do you have
the message properties set up?
That should probably be
fruits Val <s:text name="%{fruitsId.value}" />
and, for sanity checing (in case your message resources aren't set up
correctly) you should start with just
fruits Val <s:property value="%{fruitsId.value}" />

Hi,
I am trying this way:
<s:iterator id="fruitsId" status="fruitsStat"
value="fruitscolourandInfo" >
fruits KEY <s:property value="#fruitsId.key" />
<colour/>
fruits Val <s:text name="%{fruitsStat.value}" />
<colour/>
<s:iterator id="colourId" status="colourStatus"
value="fruitsId.value" >
colour <s:text name="%{top.value}" /> <colour/>
</s:iterator>
</s:iterator>
The issue is that:
Fruits key: is being displayed fine
Fruits Val: nothing is being dislayed; infact when I tried similarly
with fruits KEY even that is not being displayed. Any ideas how to get
this working.. (in fact I need to get the results in textboxes next)
Any help?
Ravi

Subject: Re: S2 NESTED iterators & FLAT HashMaps:
When you use the "iterator" tag, the value of the "id" tag becomes the
reference to the current object on that iteration(same as "top" on
this case). When iterating over a map, the object is a Map.Entry, so
you need to access the "key" and "value" properties, like
<s:iterator id="superMap" value="myMap">
Key: <s:property value="superMap.key" /> ....same as <s:property
value="key" />
Value: <s:property value="superMap.value" />....same as
<s:property value="value" />
</s:iterator>
is not a direct answer to your question, but I think your problem is
around that.
//you can always do %{superMap[top.key]} to access the value, it is
just harder to read

hi,
i have 4 hashmaps as follows:
(1). HashMap<String, HashSet<String>> treesFruitsMap = new HashMap();
(2). HashMap<String, HashSet<String>> fruitsColourMap = new HashMap();
(3). HashMap<String, String> colourVitaminMap = new HashMap();
i.e.
(1) has the mapping btw tree names and the fruits it bears (as a set
of
strings)
(2) has the mapping btw fruit name and the possible colours it can
come out
in
(3) mapping btw fruit and the vitamins it has in it.
I need to display the output as follows:
Fruit1 - Colour1 - Vitamin1
Fruit1 - Colour1 - Vitamin2
Fruit1 - Colour2 - < corresponding vitamins >
...
any idea how to go with this? I tried as follows but its not working..
<s:iterator id="frId" status="frStat"
value="frColourMap.keySet()" >
<s:iterator id="coId" status="coStatus" value="top" >
FE <s:text name="%{top}" /> <br/>
BR <s:text name="%{coStatus[top]}" /> <br/>
</s:iterator>
</s:iterator>
this is giving only the fruits names but not the colours...
pl: help.
