Everything was going OK... got my app migrated and a few things debugged.  I'm using the latest PFC files.  Was trying to debug an error when running the app from with the IDE, I decided to just copy my old pfc extension libraries and re-migrate. 

The error I was initially trying to debug is a Null Object error in the SystemError event of the application object.  The offending (only) line:

gnv_app.Event pfc_SystemError()

Things went downhill from there. Long story short, I'm now getting an error migrating the app.  The error is:

Assertion Failure
missing case in obj_get_pcode_stack_effects (twice)
File: rtengine.cpp

Then PB2021 crashes.

I tried dropping the entire target and recreating, no luck.  I also did a complete computer reboot, no luck. Same result every time I try to migrate.

Need some help here!

TIA,
~~~Tracy

Hi Tracy;

   Sounds like you might have "suspect" PowerScript code in your old PFE layer. I would return to the lastest PFC/PFE layer with your PB App code. Then re-migrate & do a full build. If that brings the App back to a runnable condition, then I mould merge the old PFE objects "as needed" but fully check the code first before replacing the current PFE layered object.

Regards ...  Chris

Thank you Chris. I started from scratch (again) with the current PFC/PFE files. I had to export a few PFE layer objects from PB 2019 app. I took care to do it one at a time... took a while! Now time to run and debug... I'm immediately running into issues with the login window... will post another question if I can't figure it out.

Thanks for the feedback! Yes, opening a new thread for another issue would be better for people to follow & focus on.
