Hi Dave,

Thank you for contacting us on this.

We are going to investigate this case, and meantime, I kindly ask you to check the file's ID that is which is related to the @RemoteAction method in your log file which you debug, and compare this ID with the ID of your Apex class and Visualforce page.

To find an ID of your Apex class or Visualforce page file, please open the project folder (you can easily navigate to it using the 'Open Folder in File Explorer' command from the context menu of your project in the Solution Explorer) and please open the related *.sfproj file using any text editor. There you would be able to check an ID of the necessary file.

Looking forward to your response.

Thank you,

Kate

Hi Kate. Thanks for the response. 

The start of the log looks like below, a bit redacted but basically the same.

The first Id on line 4 is the VF file that calls the remote action from JS. The Id near the end of this is the Apex controller that holds the remote action code.  I did just find that if I replace that first VF Id with the Apex Id, the debugger works correctly!
