alice-teacher Alice Array Elements calling Methods

[Kelly, Terri]

I have a world which is not behaving like I am expecting it to.

I have an array of automobiles called rowA[]
I have a method created for automobiles called go
In go, the first thing I have this do is say it's Sthing (this say "" +
SThing this)

If I call go with blueTruck, it works fine, the truck says blueTruck and
then moves forward

blueTruck.go()

If I call go with rowA[0].go ... Alice hangs,

So, from the test method I have

blueTruck.go()
rowA[0] = blueTruck
rowA[0].say "" + Sthing rowA[0]
rowA[0].go

Is there any reason why I should not be able to call a class level method
from an array that is of that type class?
