Hi, @btspoony

https://github.com/cocos2d/cocos2d-html5/blob/8842c38c3fe975c710d885a360e293e223f5541c/extensions/gui/scrollview/CCTableView.js#L615-L616

Why are these two lines useless?

[dingpinglv]

And about this error "Uncaught TypeError: Object # has no method 'createFramebuffer' CCGrabber.js:40"

The tip information "CanvasRenderingContext2D" means that the render mode in on Canvas mode.

I don't know why does change the cc._renderContext reference, Could you please send a demo to me(dingping.lv@cocos2d-x.org)?

about https://github.com/cocos2d/cocos2d-html5/blob/8842c38c3fe975c710d885a360e293e223f5541c/extensions/gui/scrollview/CCTableView.js#L615-L616

1. this.getBoundingBox() return cc.Rect, without the property "_origin" (cause undefined error...)
2. only this setter, no anywhere to use it

[btspoony]

sorry for issue this error "Uncaught TypeError: Object # has no method 'createFramebuffer' CCGrabber.js:40"

renderMode: 0 means webgl, 1 means canvas. i am confused with "cc._RENDER_TYPE_WEBGL = 1;"

so, this error should be occured in canvas mode, webgl mode is OK

[dingpinglv]

cc.TiledGrid3DAction supports WebGL mode only. I'll add some error information in these actions when the render mode doesn't equal WebGL

Thanks for feedback.

[dingpinglv]

@btspoony Yes, cc.Rect's "_origin" has been deleted. Thanks for reminding.
