I think your problem may be that debugging in Atelier is a bit different from Studio. Try reading:

Running and Debugging an Atelier Application:  https://cedocs.intersystems.com/atelier/latest/index.jsp?topic=%2Fcom.intersystems.atelier.help%2Fhtml%2Ftasks%2Fatelier-debug.html
 

Launch Configurations: https://cedocs.intersystems.com/atelier/latest/index.jsp?topic=%2Fcom.intersystems.atelier.help%2Fhtml%2Ftasks%2Fatelier-debug.html

Debug Perspective: https://cedocs.intersystems.com/atelier/latest/index.jsp?topic=%2Fcom.intersystems.atelier.help%2Fhtml%2Ftasks%2Fatelier-debug.html

Hope that helps,
 

Hi Mike,

Thanks for your question.

Atelier is based on the Eclipse development environment. The “Workbench User Guide” is documentation provided by Eclipse that provides basic information about using Eclipse. It is potentially useful to users of Atelier, but it is not specific to Atelier, and is not maintained by InterSystems. You may find that the “Getting Started” section of the “InterSystems Atelier User Guide” provides more Atelier-specific information.

You’ll find the latest documentation at this link:  http://docs.intersystems.com/atelier/latest/index.jsp. If you have downloaded and installed Atelier, you might want to use the documentation installed locally with the product. From the Atelier main menu, select Help > Help Contents. This will guarantee that you have all documentation improvements as of the build you have installed.

You might also want to check out the Atelier video playlist on YouTube. There are several videos there to help new users get started, with more in the pipeline.

Please don’t hesitate to return to the Developer Community with any further questions you have.

I've just posted a table of Atelier equivalents for commonly used Studio features. You might want to take a look at that.
