found the issue. Apperently you need to upload everytime the copymewithjar.needs file to the rasp same time you update the app

Yes, as it quite possible the .needs file has been changed (e.g. you added a new type of compoent and so it needs extra css/js files).

I've find it such issue in the past and maybe I can't assure 100% but maybe it seems related on using b4-bridge/debug on the app before uploading/executing the app on RPi (didn't remember how I've solved but I allways look for the needs file before running the app)

The thing is on rPi in debug mode, it starts in a subfolder (TempJars if I recall correctly). However, the www folder and the .needs file are not in that folder, so you have to copy the www + .needs file there (and give that subfolder full read/write rights).

it probably is. It would be nice if B4J bridge had some kind of 'script' functionality where you can copy additional files before running.

CustomBuildActions can be the solution: (after Compiling and Releasing the project, the needs file can be copied to RPi - a .bat that copy this file/s to a shared folder on Rpi (with Samba for ex) or creating a B4J app on Rpi to upload the needs file to the correct folder)

On B4J, there're only 2 Custom Build Actions:
1 - Before the compilation steps.
2 - Before the compiled program is executed.​
