How to save/retrieve data model variables in script or service tasks?

[mathewsmotta]

Hello all,

We're currently trying to save some data in an external database using data models. We've been successful in doing so with a simple form and Store entity task.

However, our use case is a bit more complex - the process requests calculation results from an external source through REST and we want to store the response of this request in a data model (instance? variable?) instead of a process variable. This way we could keep using the store task mapping the variables (doing so like resultJson.prop1, resultJson.prop2)

Is there a way to achieve this?

We also noticed that after a store task, the data model variable .getEntity() returns null - is that expected?
