Variables copy?

[rankorn]

I have 3 actions that work with variables:
The first one will create a List and store it in the ExecutionContext.
The second one will get it using getVariable() and add items.
The third will get it and print the List.

When I try to print the List, the items that are put in the second action are not visible. I must use setVariable() after the change to make them appear!

This behavior looks as if when I call getVariable() I get a copy of the variable.

It this the case or am I doing something wrong here?

I can't help you just want to say that I've noticed the same. The variable obtained via getVariable seems to be only a copy.

I guess this is intended...
I wonder how I can use the real references, my concerns is that those copies take time and influence performance.

Ok.

One sulotion is to use transient variables instead of normal variables that I guess, because of the persistency nature of jBPM, hold a copy.
Transient variables will always get the object reference.

If you don't need the DB, transient variables can work.
