Replacement for JbpmExpressionEvaluator

[sebastian_s]

Hello everybody,

I am looking for the right replacement for JbpmExpressionEvaluator to generate specific task names. In jBPM 3.2 it was possible to write something like the following:

String taskExpression = "Work on project #{projectname} for customer #{customername}
String taskName = JbpmExpressionEvaluator.evaluate(taskExpression, executionContext);
‍‍‍‍

with projectname and customername being process variables.

This would then evaluate to "Work on project Important Project XYZ for customer ABC" depending on the process variables.

Any hints?

Thanks in advance
Sebastian

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>).
