Debugging 2015 Online plugins

Hi,

How do we step through code of a plugin that gets triggered by another plugin?

For example, I have one plugin (call it No.1) that gets fired when a field is updated which casues another plugin (No. 2) to fire. How do we step through the code of plugin No. 2?

When using the profiler in the registration tool to debug a plugin it only steps through the current step that is assigned to the profiler.

Cheers,

Stanley
