 When you push values into an array on an object, the values of the

You've been bitten by the fact the array is copied by reference, not by
value. You should be setting the initial value for instance variables in the
constructor: http://pastie.caboo.se/89338

I'm not sure if this is something we should fix or not. In a way, the
framework might deal with this situations in order to follow the POLS
(principle of least surprise). We need to discuss this internally.

Anyway, do as I suggested for now. This might change in release 1.6.1.

There is nothing to fix here.  This is the exact problem that  
constructors solve.  I don't think it's surprising, and we won't be  
changing it.
