Hello,

I'm getting some unexpected results when 2 clients ( A and B ) try to execute the same script at approximately the same time:

var myChallenge = Spark.getChallenge( Spark.data.challengeInstanceId );

Spark.lock( myChallenge );

// Log.
if ( Spark.getPlayer().getPlayerId() == myChallenge .getChallengedPlayerIds()[ 0 ]  )
    Spark.getLog().debug( "I'm Player A" );
else
    Spark.getLog().debug( "I'm Player B" );

// Save this player's actions.
var playerActions = Spark.getData().PLAYER_ACTIONS;
myChallenge .setPrivateData( Spark.getPlayer().getPlayerId(), playerActions );

// Log.
var playerA_actions = myChallenge .getPrivateData( myChallenge .getChallengedPlayerIds()[ 0 ] );
var playerB_actions = myChallenge .getPrivateData( myChallenge .getChallengerId() );
if ( playerA_actions == null )
    Spark.getLog().debug( "Player A actions = NULL" );
if ( playerB_actions == null )
    Spark.getLog().debug( "Player B actions = NULL" );

Spark.unlock( myChallenge );

If  A gets the lock first, I'd expect to obtain the following output on the log:

I'm Player A

Player B actions = NULL

I'm Player B

But instead of that, sometimes (not most of the time) I get the following output:

I'm Player A

Player B actions = NULL

I'm Player B

Player A actions = NULL

What do you think might me causing this behaviour?

Thanks for your help!

Jon

Sorry, the script was missing some lines!  

var myChallenge = Spark.getChallenge( Spark.data.challengeInstanceId );
 
Spark.lock( myChallenge );
 
// Log.
if ( Spark.getPlayer().getPlayerId() == myChallenge.getChallengedPlayerIds()[ 0 ]  )
    Spark.getLog().debug( "I'm Player A" );
else
    Spark.getLog().debug( "I'm Player B" );
 
// Save this player's actions.
var playerActions = Spark.getData().PLAYER_ACTIONS;
myChallenge .setPrivateData( Spark.getPlayer().getPlayerId(), playerActions );
 
// Log.
var playerA_actions = myChallenge .getPrivateData( myChallenge .getChallengedPlayerIds()[ 0 ] );
var playerB_actions = myChallenge .getPrivateData( myChallenge .getChallengerId() );
if ( playerA_actions == null )
    Spark.getLog().debug( "Player A actions = NULL" );
if ( playerB_actions == null )
    Spark.getLog().debug( "Player B actions = NULL" );

if (  playerA_actions != null &&  playerB_actions != null )
{
   // TODO: If both player actions are present, send the actions to each player.

    myChallenge.removePrivateData( myChallenge.getChallengedPlayerIds()[ 0 ] );
    myChallenge.removePrivateData( myChallenge.getChallengerId() );
}
 
Spark.unlock( myChallenge );

Has this issue been resolved? We too are seeing unexpected results during concurrency testing.
