share application context with modern and classic listener fails to execute error template.
Attached is a very simple test that you can unzip and run in CommandBox to see the issue. Basically they have multiple applications sharing the same app name but some use Application.cfc and some use Application.cfm. Both apps in this sample are throwing an error (on purpose) and their error handling works initially. However, after you hit the CFC site, the CFM site will stop working and only display a blank page. This error put in the logs is below.
