getEx() every time null

[General Api]

Every time I try to get exchange price, from a Java code, as well as from virtualizer, the response is null.
For example see this simple screenshot of virtualizer.

Click on the little information icon (on the right hand side).

Then, when the dialog box pops up, select one of the selections and the prices should be displayed.

It shows this... (see attached). notice, empty prices.

Thank you. I didn't click on each selection.

However I can't figure out the problem in Java code. I get a list of MarketBooks

List<MarketBook> marketBookReturn = jsonOperations.listMarketBook(marketIds, priceProjection,orderProjection, matchProjection, currencyCode,applicationKey, sessionToken);

Then get a specific market book from list

MarketBook mb = marketBookReturn.get(0);

which in turn gives me runners of that marketbook

List<Runner> runners = mb.getRunners();

But the problem comes then.

for (Runner runner : runners) {
System.out.println(runner.getSelectionId()) ; //gives correct answer
System.out.println("Last price traded: " + runner.getLastPriceTraded()) ; // this is also ok
System.out.println("Exchange price: " + runner.getEx()) ; //but this one returns null
}

What have you got set for priceProjection, matchProjection and currencyCode in your listMarketBook call?

What is the code for the listMarketBook function?

What is the code for the getEx function?

here's my ( REST ) query to listMarketBook, which gets, amongst other things, the best Back Price and Best Lay Price:

https://api.betfair.com/exchange/betting/rest/v1.0/listMarketBook/ {"priceProjection":{"exBestOffersOverrides":{"bestPri
cesDepth":1},"priceData":["EX_BEST_OFFERS"],"virtualise":false},"matchProjection":"ROLLED_UP_BY_AVG_PRICE","orderProject
ion":"ALL","marketIds":["1.114267385"]}

I used codes from
https://github.com/betfair/API-NG-sa...ee/master/java.

which is referenced from
https://api.developer.betfair.com/se...mq5qye0ni/Java

-------- Projections --------------------------
OrderProjection orderProjection = null;
MatchProjection matchProjection = null;
String currencyCode = null;

PriceProjection priceProjection = new PriceProjection();
Set<PriceData> priceData = new HashSet<PriceData>();
priceData.add(PriceData.EX_BEST_OFFERS);
priceProjection.setPriceData(priceData);
priceProjection.setVirtualise(true);

ExBestOfferOverRides exbest = new ExBestOfferOverRides() ;
exbest.setBestPricesDepth(1) ;
exbest.setRollupModel(RollupModel.STAKE);
priceProjection.setExBestOfferOverRides(exbest);

------------ listMarketBook ---------------------
public List<MarketBook> listMarketBook(List<String> marketIds, PriceProjection priceProjection, OrderProjection orderProjection, MatchProjection matchProjection, String currencyCode, String appKey, String ssoId) throws APINGException {
Map<String, Object> params = new HashMap<String, Object>();
params.put(LOCALE, locale);
params.put(MARKET_IDS, marketIds);
String result = getInstance().makeRequest(ApiNgOperation.LISTMARKE TBOOK.getOperationName(), params, appKey, ssoId);
if(ApiNGDemo.isDebug())
System.out.println("\nResponse: "+result);
ListMarketBooksContainer container = JsonConverter.convertFromJson(result,ListMarketBoo ksContainer.class);
if(container.getError() != null)
throw container.getError().getData().getAPINGException() ;

return container.getResult();
-------------------------------------------------------------
getEx(), is a method of Runner.java which returns object of type ExchangePrices.
