Moving from 2.4 to 3.0

I can't recall anything major between 2.4.x and 3.0.x.

Have you tried putting in some Sys.println() calls to see how far the app gets? Maybe in various initialize() calls to start.

I found the issue by discretely removing code until exception was not raised anymore.

Then, targeting line by line, I found the issue that was linked to an Object type issue.

I have no idea why it was not raised in previous version but I don't really.

So bad that debugger doesn't raise exception details...

Thank you jim for you answer, I found the problem before but I'm please to hear that you don't recall any big changes.

Just curious, but what was the issue?

3.0.x does add some additional checking at compile time, but can't recall anything at runtime:

New automatic symbol checking (ASC) checks your code for mis-typed symbols at compile time, but keeps the dynamic functionality of Monkey C

The issue was that I was passing an object in a method that was doing home made mathematical exponential rolling average.

A miss auto-complation that was not tested properly at that time and that was passing a HeartRateData object in a sensor update method that not made for handling this type...

But no compiling error on that.
