Hi,
I've noticed that jBPM trims whitespace and removes newlines from scripts (or any action/delegation XML config).
With scripts, this can be a bit annoying for multiple reasons:
- since there are no separate lines anymore, it makes error reporting by the script engine less readable
- the meaning of things might be changed, e.g. a string like " abc def" will become " abc def".
- single-line comments using "//" are not possible.
I've tracked the cause of this down to the creation of the class Delegation, where an XMLWriter is instantiated using "createCompactFormat" to create the serialized configuration:
XMLWriter xmlWriter = new XMLWriter( stringWriter, OutputFormat.createCompactFormat() );
I don't know if removal of the compact format usage would cause any issues (e.g. other places relying on the whitespace being removed) besides a little bit more whitespace stored in the database, but otherwise I would very much appreciate if it could be removed. Or maybe some attribute could be added to the action element to indicate the whitespace-treatment preference.
You can change it and try running all the tests. I'm curious about the results
