Hi all, process variables are defined as name-type pairs.
>From the Eclipse plugin I can see that types are defined by means of a Java class, however engine API deals with them as objects (Map<String, Object>).
The question is: who/when does check type consistency ? Is it an engine responsability or a task one ?
Should a task check received parameter type of all input parameters or is it already done by the engine ?
What happens when constrains meet a wrong type at runtime ?
