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.

Oops.
I had to click on every single runner to get prices of that runner in virtualizer.
So the problem is only in may java code, which I explain in the next post int this same thread.

[General Api]

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
}
Edit

Hi General API, have you found a solution yet (I'm stuck on the same)?
I believe the problem is within the request itself: a System.out as below

System.out.println("ListMarketBook return:" + marketBookReturn.toString());

will return the following:

ListMarketBook return:[{marketId=1.114445964,isMarketDataDelayed=false,status=OPEN,betDelay=0,bspReconciled=false,complete=true,inplay=false,numberOfWinners=1,numberOfRunners=8,numberOfActiveRunners=8,lastMatchTime=Sat Jun 28 08:07:01 BST 2014,totalMatched=3183.47,totalAvailable=21019.54,crossMatching=false,runnersVoidable=false,version=771507669,runners=[{selectionId=8574934,handicap=0.0,status=ACTIVE,adjustmentFactor=40.7,lastPriceTraded=2.36,totalMatched=2114.53,removalDate=null,sp=null,ex=null,orders=null,matches=null,}, {selectionId=8606737,handicap=0.0,status=ACTIVE,adjustmentFactor=33.3,lastPriceTraded=3.25,totalMatched=755.53,removalDate=null,sp=null,ex=null,orders=null,matches=null,}, {selectionId=8632309,handicap=0.0,status=ACTIVE,adjustmentFactor=7.7,lastPriceTraded=12.0,totalMatched=97.22,removalDate=null,sp=null,ex=null,orders=null,matches=null,}, {selectionId=8469653,handicap=0.0,status=ACTIVE,adjustmentFactor=6.1,lastPriceTraded=19.0,totalMatched=63.37,removalDate=null,sp=null,ex=null,orders=null,matches=null,}, {selectionId=8652132,handicap=0.0,status=ACTIVE,adjustmentFactor=5.6,lastPriceTraded=18.5,totalMatched=50.9,removalDate=null,sp=null,ex=null,orders=null,matches=null,}, {selectionId=8652131,handicap=0.0,status=ACTIVE,adjustmentFactor=3.8,lastPriceTraded=7.0,totalMatched=57.18,removalDate=null,sp=null,ex=null,orders=null,matches=null,}, {selectionId=8652130,handicap=0.0,status=ACTIVE,adjustmentFactor=2.1,lastPriceTraded=44.0,totalMatched=18.47,removalDate=null,sp=null,ex=null,orders=null,matches=null,}, {selectionId=8521307,handicap=0.0,status=ACTIVE,adjustmentFactor=0.7,lastPriceTraded=190.0,totalMatched=26.24,removalDate=null,sp=null,ex=null,orders=null,matches=null,}],}]

Observe the ex=null. Maybe missing some parameters when make the request.

when yo do runner.getEx() what is retuned is an Object that contains, two json lists:

availableToLay
and
availableToBack

so in my app ( i use json.simple), I have something like:

double bestLayPrice  = -1;
double bestBackPrice  = -1;
double lastMatchedPrice  = -1;

if(runner.containsKey("lastPriceTraded"))
	lastMatchedPrice = (Double)runner.get("lastPriceTraded");

JSONObject exObject = (JSONObject)runner.get("ex");
JSONObject priceObject = null;

JSONArray priceArray = (JSONArray)exObject.get("availableToLay");

if(priceArray != null && priceArray.size() > 0)
	{
		priceObject = (JSONObject)priceArray.get(0);
		
		if(priceObject != null)
			bestLayPrice = (Double)priceObject.get("price");
	}
					
priceArray = (JSONArray)exObject.get("availableToBack");

if(priceArray != null && priceArray.size() > 0)
	{
		priceObject = (JSONObject)priceArray.get(0);

		if(priceObject != null)
			bestBackPrice = (Double)priceObject.get("price");
	}

hope that makes some kind of sense!

Ooops, should have read your post properly, so you're getting ex=null

that must be something missing from your request params as altisw says.

here's my request, which does get the ex object:

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":["1.114453677"]}

which returns:

Thanks for your replies gus.
From what I understood, to get prices, you have to set priceData as
priceData.add(PriceData.EX_BEST_OFFERS);
This will set runners to display the prices when selected.
I'm using Java Sample code (and not a programmer by profession).
Haven't seen on the code where ExchangePrices object is created(this is where null object is coming from) .
Thanks.

[altisw]

here's my request, which does get the ex object:

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":["1.114453677"]}

How do you get the code of request?
Thanks..
