Resolution: Won't Fix
For the moment I will close it if someone interested on it can create a new issue.
> Use of Hashtable in SOAPClientEngine doesn't allow nulls.

> Interestingly although the method getResponseParams returns a Map, it internally initializes a member variable, mRet with the type "Map", but implementation of Hashtable. The use of a Hashtable in the SOAPClientEngine prevents the return of "null" values in key/value pairs.
> Example: Some service call retrieves an entity - and it then uses the following code:
> String entityId = (String)context.get("entityId");
> if(entityId!=null) {
> try {
> GenericValue myEntity =
> delegator.findByPrimaryKeyCache("MyEntity", UtilMisc.toMap("entityId",entityId));
> Map result = ServiceUtil.returnSuccess();
> result.putAll(myEntity);
> ...
> return result;
> Now, say that one of the fields of the underlying entity is blank - null - in the database. Upon thunking thru to the SOAPClientEngine - that Map defined in the 'result' appears to be remapped into a Hashtable in the method call:
> private Map getResponseParams(Message respMessage) {
> ...
> while (p.hasNext()) {
> RPCParam param = (RPCParam) p.next();
> mRet.put(param.getName(), param.getValue());
> System.out.println(param.getName() + "=" + param.getValue());
> }
> Of course, in attempting to 'put' the null valued key onto the Hashtable - a null pointer exception is thrown. Simply changing mRet to use a HashMap as opposed to Hashtable seems to work fine, and correctly handles null valued keys.
