I'm playing with BonitaBPMCommunity-7.2.3 for a wile and
I found some very annoying things:
* Very poor and inflexible input validation (input constrains). Just one static error message and no access to business/process variables.
* Expression editor is to small for script editing.
* Bad navigation. To many clicks if you want to edit some scripts especially in connectors.
* It is no way to see the main window or something else behind if expression editor is open. A popup window is not good for it anyway.
