Hello,

I have the same issue. I followed what was described here : https://community.alfresco.com/thread/232467-adding-custom-functions-to-expressionmanager#comment-818540 but I have the exception : org.activiti.engine.impl.javax.el.ELException: Expression uses functions, but no function mapper was provided

What kind of magic are you talking about ?

Thank you for you answer !
