System.js#2015

The line

var n = b2Vec2.Add(p, b2Vec2.Subtract(t, v));

should be

var n = b2Vec2.Add(p, b2Vec2.Multiply(t, v));

There is no possibility to create MassData instance because array element 
missing:
{"trimmed":"MassData","name":"b2MassData","def":b2MassData}

What steps will reproduce the problem?

1. Try using the CreateParticleGroup by the b2ParticleDef.b2_elasticParticle 
flag. 
2. DestroyParticlesInGroup.


What is the expected output? What do you see instead?

I was expect great particle. but i saw exception instead.


What version of the product are you using? On what operating system?

I am using the jsliquidfun.js.
This is checked out from the svn repository before a few days.

I am using Mac OS X 10.7.5 and Safari 6.1.5


Please provide any additional information below.

I have some result at this time.

1. The b2StackQueue's capacity is not capacity.

That is simply initial size.
the b2StackQueue is growable.

2. The b2ParticleSystem's some buffer has null condition.

So check the buffer is null or not.
I caught a many exception at a function SolveZombie's new indexing.

3. The b2ParticleSystem.b2_invalidParticleIndex is missing.

So Buffer.collapse result suspicious.
I defined it.

A modification of the above, it seems to be removed an exception.

I'm glad to help if something.

b2CircleShape TestPoint method do not work.

It will be great if this port will replace the box2dweb in new version of 
cocos2d-js engine :))
They are working on it right now..

in-version-box2dweb-2-1-a-3-box2d-v2-3-1r3

I think this issue is in this version as well.

I used this code to test it:

When I try to add jsbox2d.min.js to Cocos Code IDE(based on Eclipse) it hang up
