Calling spring bean from alfresco activiti process

[younis15]

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'
at org.activiti.engine.impl.juel.AstIdentifier.eval(AstIdentifier.java:83)
at org.activiti.engine.impl.juel.AstMethod.invoke(AstMethod.java:79)

I got it

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

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

<!– Limit the visible beans in expressions –>


<property name="beans">
    <map>
        <entry key="services" value-ref="ServiceRegistry" />
        <entry key="sequenceUtil" value-ref="sequenceUtil" />
    </map>    
</property>

    <property name="customTypes">
        <list>
            <ref bean="activitiScriptNodeType" />
            <ref bean="activitiScriptNodeListType" />
        </list>
    </property>
    <property name="customPreBPMNParseListeners">
        <list>
            <ref bean="activitiParseListener" />
        </list>
    </property>
</bean>

Hello,

Have the same problem. Following Nick Smith's slides, it should be enough extending the BaseJavaDelegate, but it's not…. still facing the same issue. Hope the Alfresco 4 release (not the beta one) solves this problem….
