Declared value has type org.activiti.engine.impl.el.FixedValue, while expecting org.activiti.engine.delegate.Expression

My code works fine on community version. But on trial version of enterprise I am getting following error . Incompatible type set on field declaration 'jarfilepath' for class DataflowRunner. Declared value has type org.activiti.engine.impl.el.FixedValue, while expecting org.activiti.engine.delegat

I think your JavaDelegate is using an Expression with the wrong class (there are two Expression classes in Activiti), you should switch to the other.

In Activiti v6, we've removed this duplication, there is only one left.

I am using these classes
import org.activiti.engine.delegate.Expression;
import org.activiti.engine.delegate.JavaDelegate;
Is this wrong one? However with community version my code works fine. This issue comes with trial license of enterprise .

Thanks

I tested with org.activiti.engine.impl.el.Expression as well. Still same error.

And if I use

activiti:field name="namexyz" expression="${myBean.getName()}" then it throws error

Incompatible type set on field declaration 'namexyz' for class DataflowRunner. Declared value has type org.activiti.engine.impl.el.JuelExpression, while expecting org.activiti.engine.impl.el.Expression
