Dynamic injcection of values does not work in Spring context

Hi,we are setting up an application using Activiti and Spring. We have problems in injecting dynamic variables at runtime. The variant:<serviceTask id="javaService" name="My Java Service Task" activiti:class="xxx.MyTask" > <extensionElements>

If youre using SpringProcessEngineCOnfiguration, the full spring-context (the context where the activiti engine is defined) is available (make sure you don't use a regular non-spring configuration). All expressions are resolved at RUNTIME, so fetched from the app-context when the expression is evaluated = when service-task actually runs.

We are actually using SpringProcessEngineConfiguration and the Spring context is available with the only exception when we use activiti:class in our serviceTask. In this case the Spring context is empty.

I see what you mean… The injections are only performed on classes that are instantiated by activiti itself. As you know, this only happens one time (the Expression objects are injected, value resolving happens based on the DelegateExecution) -> single javaDelegate is used for all processes.

Since the delegateExpression can return anything and is potentially already configured, no field injections are done on this. All process-context can be fetched from the DelegateExecution, all non-process dependant stuff can be wired in by Spring I guess…
