[stringtemplate-interest] Simple example of list iteration

[Richard Apodaca]

To follow up with something easier to test/debug - here's a complete JUnit
test that shows the source of my confusion:

https://gist.github.com/1943633

The first test passes as I expect. The second test gives the error:

context [template] 1:1 no such template: /_sub1

context [template] 1:8 passed 1 arg(s) to template null with 0 declared
arg(s)

context [template] 1:1 passed 1 arg(s) to template null with 0 declared
arg(s)

context [template] 1:1 passed 1 arg(s) to template null with 0 declared
arg(s)

context [template] 1:1 passed 1 arg(s) to template null with 0 declared
arg(s)


Any ideas?


Thanks,

Rich
