Parameters will returns String[] but not string check out that might be
causing the problem.

Re: struts2 string to map conversion

[Li Ying]

What is your client side code (JSP)?

In OGNL expression, a value assignment is something like:
aMap[aKey] = aValue

So, you need create HTML code like:
input name=aMap[aKey] value=aValue /

On the server side, the OGNL expression will be converted into Java
method invoking like:
yourAction.getAMap().put(aKey, aValue)

Unfortunately, the Java generic system don't know the element data
type of your Map,
so, the data type for [aKey] and [aValue] may be a problem.

I suggest you just declare the map as MapString, String, and do the
conversion by yourself.

All I talked above are not tested, just suggestion.
You need do the test and check if it is correct.

 any body knows how to use Struts2 TypeConversion(in xwork libs) to
 convert a parameter string to a hashmap object?
 I tried this:

 @TypeConversion(key = phone, rule = ConversionRule.MAP, converter =
 java.lang.String)
 public void setHmss(HashMapString, Object hmso) {
                this.hmso = hmso;
 }

 but no convert had it done.how?any suggestion?

Have you read through this -

http://struts.apache.org/2.x/docs/ognl-basics.html

The type conversion is generally called automagically.
