Hi,

Create/update serializable variable through REST API is supported. Have a look on the following jUnit test in activiti source

Thanks for the reply! The test code gave me some ideas, but the problem is I'm calling the REST api from an angularjs client, not from Java. I'm assuming I have 2 options:
1. find a way to call restful from angular with content-type application/octet-stream
2. I'm still interested in finding an example to do the following:
"In the new REST-api, this will be possible because there is a pluggable mechanism for variable-types. It will allow you to plug is some code to create a POJO based on a JSON-representation (exposed as a Map). This will be available in 5.13 of 5.14."

Any suggestions is much appreciated!
