No Sure whether this is a bug.

I tried initializing the process in spring boot without deploying the process definition into the db. It works fine.. no issues when the java operation gets called.

However, after deploying the process definition into the db, it keeps complaining "Unknown property used in expression:"

tried all the scenarios

#{timeData.sayHello()}
${timeData.sayHello()}
${<packagename>.timeData.sayHello()}
#{<packagename>.timeData.sayHello()}

timeData as java delegate class
timeData as Serialization class

No luck

Hi Andat,

Is timeData registered ad spring been in the spring app context somewhere?
(Can you check it in expression resolver?)

Martin - Yes it is annotated @Bean in the Config class

Hi,

Did you check whether expression resolver has access to this bean?
See following jUnit tests org.activiti.spring.test.servicetask.ServiceTaskSpringDelegationTest
