How is the list of process-variables stored? If it's an array-list of String, activiti will store it as a serializable. Afterwards, when calling getVariable() you can just cast to List<Stirng> and use it I guess…

Hi,

I got below Exception

[Faces Servlet]] (http-localhost-127.0.0.1-8080-1) Servlet.service() for servlet Faces Servlet threw exception: java.lang.ClassCastException: [Ljava.lang.String; cannot be cast to java.util.List

how to cast Serializable object to List<String>.

Please check the exception before posting it blindly to the forum. I was just "guessing" it was a list. Clearly, it's not a list but an array of strings (hence the "Ljava.lang.String" in the CCException)
