Reply to: XMetaL Developer: Debug Application CustomizationJanuary 20, 2018 at 2:03 am
This is a known limitation. It is documented in the readme for XMetaL Developer as “Application-level XAC debugging does not work”.
You will need to deploy the MCR file in this case, and if you need to debug it you can insert a debugger statement into the file at the location you want to trigger script debugging. It isn't as elegant as being able to start it from Visual Studio with the ability to set a break point but it should give you script debugging.
For JScript insert the keyword “debugger” (without quotes) at the line you wish to trigger the debugger.
