How many people use Configuration Change Templates?

I've tried to use configuration change templates, but find the lack of error logging makes this feature unusable except for the most simple scripts.  An example is I need to change a DHCP helper in every router.  How do I make sure this change was successful on every router?  Today, you must look the output of every router run in CCT, or you need to create a compliance policy that looks for your change. 

What I've proposed in the past is to use standard "Expect" scripting construct that makes the change then waits for (or expects) some feedback to ensure the command worked (or capture the failure message) and end with a errorlevel so you know something is the script didn't execute as "expected".

How many people actually use this feature?  I don't see alot of scripts posted to Thwack, so I don't think its overly used.

I feel your pain.  I started trying to create a template today and I'm having a hard time trying to figure out how to do something that should be simple.  I wish there was more detailed documentation for the language.  I have no problem with SW creating their own scripting language for NCM but they really need to provide more documentation that a section in the admin guide.  For example:

"Manipulating Strings

You can use the functions substring, strlength, indexof, setoctet, getoctet to manipulate strings within your config change template scripts."

Ok, so I can use those functions to manipulate a string but how do I use them?  In the example it provides a way to use setoctet.  It would be nice if we had documentation that showed each function, the parameters it takes, and how to use it. 

In my example, I want to enter one command for a device that's running IOS 12 and another command for IOS 15.
