Yasser Zamani updated WW-4176:
------------------------------
Attachment: WW-4176-proposal.patch
Maybe we can have an improvement for {{ParametersInterceptor}}!
I attached a proposal patch as my suggestion. After applying that,
{{ParametersInterceptor}} tries to fix parameter names by covering string
indices with single-quotes e.g [2a_z] -> ['2a_z'].
I tested it with latest code and works as expected.

> Sending Map from javascript/jsp to JSON Action, when the Keys are numeric
> everything works, when the keys are Strings then these entries are thrown
> away while the mapping process in the JSON Action takes place.
> Important note: If i create a map in the JSON Action and send it to the
> client everything is ok.
> alert which shows the Server generated JSON:
> {noformat}
> ServerJSON{"1":"1","2":"ANOTHERVALUE","ANOTHERKEY":"1","KEY":"VALUE"}
> {noformat}
> If i look into the sended data from javascript side in Eclipse i see in debug
> mode:
> {noformat}
> this=>myJSONMap:{2=[Ljava.lang.String;@3caf7a1f,
> 23=[Ljava.lang.String;@247aa859}
> {noformat}
> Alert shows on client side:
> {noformat}
> ClientJSON{"2":["ANOTHERVALUE"],"23":["1"]}
> {noformat}
> Hope it's clear where the problem is. Bug or misunderstood anything?
> Would like to have a List of keys,values where the keys can be
> String/Long/Int and the values can be String/Long/int.
> The direction Server generated Map=>JSON is ok, sending the same from client
> side will lose the entries with a String key.
> Further i tried also to specify my Map like
> {code:java}
> private Map<String, String> propertyValueMap = new LinkedHashMap<String,
> String>();
> {code}
> and set the getters/setters but don't work either.
> Here is a part of my code:
> JSP PAGE:
> {code:html}
> <form action="" id="testForm1">
> testForm1<input type="submit"/>
> </form>
> <script>
> $("#testForm1").submit(function(event){
> event.preventDefault(); //Cancel the default action (navigation) of the click.
> var data={"1":"1","2":"ANOTHERVALUE","ANOTHERKEY":"1","KEY":"VALUE"};
> var sentData={};
> sentData["myJSONMap"]=data;
> $.getJSON("<s:url namespace="/ajax" action="testMap"/>", sentData
> ,function(data3) {
> alert("Server generated JSON"+JSON.stringify(data3.mymap));
> alert("Client generated JSON"+JSON.stringify(data3.myJSONMap));
> });
> });
> {code}
> JSON Action config:
