Calling spring bean from alfresco activiti process

Within alfresco activiti, could I call a spring bean using the servicetask like :

<serviceTask id="assignApplicationId" name="Assign Application Id"
  activiti:expression="${sequenceUtil.getOutboundId(task.id)}"
  activiti:resultVariable="OutboundWF_ApplicationNumber"/>

however, in my custom context I declared the

sequenceUtil

as the following:

<bean id="sequenceUtil" name="sequenceUtil" class="com.tts.mersal.presentation.bean.dialog.util.SequenceUtil">
    <property name="searchService">
        <ref bean="searchService" />
    </property>
    <property name="nodeService">
        <ref bean="nodeService" />
    </property>
    <property name="workflowService">
        <ref bean="WorkflowService" />
    </property>    
</bean>

Actually I got the following exception

org.activiti.engine.impl.javax.el.PropertyNotFoundException: Cannot resolve identifier 'sequenceUtil'

I got it

I have to override the  activitiProcessEngineConfiguration bean to include my custom bean within beans property

<!– –>
<!– Activiti Process Engine –>
<!– –>
<bean id="activitiProcessEngineConfiguration"
&nbsp;&nbsp;&nbsp; class="org.alfresco.repo.workflow.activiti.AlfrescoProcessEngineConfiguration">
&nbsp;&nbsp;&nbsp; <property name="dataSource" ref="wrappedDataSource" />
&nbsp;&nbsp;&nbsp; <property name="transactionManager" ref="transactionManager" />
&nbsp;&nbsp;&nbsp; <property name="databaseSchemaUpdate" value="${db.schema.update}" />
&nbsp;&nbsp;&nbsp; <property name="history" value="full" />
&nbsp;&nbsp;&nbsp; <property name="jobExecutorActivate" value="true" />

<!– Limit the visible beans in expressions –>


<property name="beans">
