I hope you're looking for the Activiti counterpart of the JbpmExpressionResolver ?

Take a look at the class "org.activiti.engine.impl.el.ExpressionManager". You can subclass this (and add custom ELResolvers to resolve variables in expressions the way you want). The custom ExpressionManager can be set on the ProcessEngineConfiguration.

A good example is the org.activiti.spring.ProcessEngineFactoryBean we ship, it set's a custom expression manager as well (org.activiti.spring.SpringExpressionManager.SpringExpressionManager(ApplicationContext, Map<Object, Object>).
