Yes, I tried that too, but it doesn't matter which data type I use, it always saves that property as double into the database.

At the moment, I'm trying to reimplement my task logic using a custom Java TaskListener.

Everything worked using Java.
So this is the way to go…

But I think the execution javascript root object should be able to deal correctly with ootb properties.
Maybe including a new parameter for execution.setVariable method, like:

Do you think we can wait for something like that?

Well, the cheesy answer is that we happily accept pull requests 😉 That's the quickest way to get it in. Otherwise, it will have to battle with other priorities … and frankly at the moment there are some other areas that need a lot of love right now :s
