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>
                       <activiti:field name="user">
                            <activiti:expression>${method.foo()}</activiti:expression>
                       </activiti:field>
           </extensionElements>
</serviceTask>
‍‍‍‍‍‍‍‍‍‍‍

works fine but the execute method in "xxx.MyTask" is executed outside our Spring context. That means that Spring injections do not work.
In the variant:

<serviceTask id="javaService"
             name="My Java Service Task"
             activiti:delegateExpression="${mybean}">
            <extensionElements>
                       <activiti:field name="user">
                            <activiti:expression>${method.foo()}</activiti:expression>
                       </activiti:field>
           </extensionElements>
</serviceTask>
‍‍‍‍‍‍‍‍‍‍‍

the task "${mybean}" is executed in our Spring context, but the injection of the variable "user" does not work. Is there any possibility (existing or planned) to have dynamic variable injection and the Spring context at the same time?

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.
