Use Spine in Cocos2dx

In cocos2dx, I use the class skeletonAnimation to create the skeleton animation which uses the resources exported by spine. We know the class skeletonAnimation is the subclass of node not is sprite.
How to do to make the skeleton animation flip the node as it like to use the method setFlippedX() in sprite node.

Error In Spine Animation

I am facing a problem while animating characters Spine 2.1.01 Professional. When I export the JSON file (imported on Cocos-2d-x), some images are getting displayed when they are not supposed to...and some others are disappearing when they should be visible (on animation).

Any ideas/suggestions would be really appreciated. I'm totally stuck!

Unable to render spine::SkeletonAniamtion with a cocos2d::Label child

I am using spine 1.9 to create skeleton animations and render with cocos2d-x v3.2. My skeletons contain skinnedmesh, I'm not able use the spine-cocos2dx runtime released with cocos2dx as the runtime is of an old version. I copied the latest spine-cocos2dx 3.2 runtime source and replaced files under cocos/editor-support/spine foler, after doing so my skeleton rendered.

But the program crashed after I added some nodes to spine::SkeletonAnimation node. After some investigations I found it only happen when,

• My scene has at least two SkeletonAnimation nodes.
• Each SkeletonAnimation node has a cocos2d::Label as child.

Sample code:

    auto m1 = spine::SkeletonAnimation::createWithFile("1001.json", "1001.atlas", 0.5f);
    auto l1 = Label::createWithTTF(ttfConfig, "1234567");
    m1->addChild(l1);
    this->addChild(m1);

    auto m2 = spine::SkeletonAnimation::createWithFile("1002.json", "1002.atlas", 0.5f);
    auto l2 = Label::createWithTTF(ttfConfig, "123456789");
    m2->addChild(l2);
    this->addChild(m2);

And the error message from console:

    cocos2d: OpenGL error 0x0502 in /Users/xtjiao/Documents/client/cocos2d/cocos/editor-support/spine/PolygonBatch.cpp flush 111
    cocos2d: OpenGL error 0x0502 in /Users/xtjiao/Documents/client/cocos2d/cocos/editor-support/spine/PolygonBatch.cpp flush 111
    ...

It seems related to PolygonBatch class and draw method of cocos2dx classes, but as I'm not familiar with opengl and low level cocos2dx, it's hard for me to have further investigation, hope some expert can help.

Thanks!
