I want to pass context inside super method calling.

For ex.

@api.multi

def write(self, vals)

    ctx = self._context or {}

    ctx.update({'key':'value'})

    res = super(product_product, self).with_context(ctx).write(vals) # It is going into infinite recursion.

#    res = super(product_product, self).write(vals).with_context(ctx) # It is not passing updated context to super method. 

    return res

Any one give proper way to pass context in super method call ?

thanks.
