By kohske:

Now the default behavior of the orders looks begin changed.

```
df <- data.frame(
x = factor(c(1, 1, 2, 2)),
y = 1:4,
a = c("a", "b", "b", "a")
)

df <- data.frame(
x = factor(c(1, 1, 2, 2)),
y = 1:4,
a = c("a", "b", "b", "a")
)

ggplot(df, aes(x, y, fill = a)) + geom_bar(stat="identity", position = "dodge") # a b b a
ggplot(df, aes(x, y, fill = a, order = a)) + geom_bar(stat="identity", position = "dodge") # a b a b
```

Is this a desired behavior?
