org.activiti.engine.ActivitiException: Unknown property used in expression:

[ad1]

I have a simple  java class annotated as @component that i am referring in service task using the following settings:

Task Type : Expression
Expression : ${org.activiti.timeData.sayHello()}

The Process fails with error org.activiti.engine.ActivitiException: Unknown property used in expression: ${timeData.sayHello()}

I had tried this before in other processes and it had worked. The error trace  thrown does not give any clues

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
