You didn't say what those expectations were, but I'm guessing you hoped the counter would retain its value across multiple evaluations of the template. Perhaps that's why you used a member variable for your counter instead of a local variable. You should expect, however, that every time you invoke the template() or inline_template() function, a new ERB instance will be created to evaluate the given template, so even if you worked around the re-initialization of your counter, I would not expect a continuous sequence across multiple template evaluations. Supposing that you have all the data you want to sequence in one place, one possibility could be to generate your content all in one template. If you don't have it all in one place, on the other hand, and you can't assign sequence numbers manually, then I am skeptical about sequence numbers being useful to you / doing what you want even if you could generate them. If you tell us more about the problem then maybe we'll have better-targeted suggestions. John -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.
