Ease actions does not work in game

Hello,
I started using the cocostudio 1.2.0.1 yesterday, and i found it is supported the ease actions ( bounce, elastic, … ), i really like it, but after i design it and put it in the game, the action run with linear, not ease at all.
p/s: i am using this function ( ActionManager::shareManager()->playActionByName ) to play anim. it it correct?
Thanks in advance

There is a new class CCArmatureDataManager in namespace cocos2d::extension;
CCArmatureDataManager::sharedArmatureDataManager()->addArmatureFileInfo(“HeroAnimation0.png”,“HeroAnimation0.plist”,“Hero.ExportJson”);
CCArmature *armature = CCArmature::create(“Hero”);
armature->getAnimation()->playByIndex(1);
armature->setScale(0.5f);
armature->setPosition(ccp(visibleSize.width * 0.5, visibleSize.height * 0.5));
this->addChild(armature,2);
