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)

There is a much better way to map bean names to el epressions. At least for alfresco
5.2
.
Originally activitiProcessEngineConfiguration
defined like that:
<bean id="activitiProcessEngineConfiguration" class="org.alfresco.repo.workflow.activiti.AlfrescoProcessEngineConfiguration">
<!-- Limit the visible beans in expressions -->
<property name="beans" ref="activitiBeanRegistry" />
</bean>
Where activitiBeanRegistry
defined like that:
<util:map id="activitiBeanRegistry" map-class="java.util.HashMap">
<entry key="services" value-ref="ServiceRegistry" />
</util:map>
So you can easy add your beans with names without touching original activitiProcessEngineConfiguration
. Like that:
<bean id="my.activitiBeanRegistry" class="org.springframework.beans.factory.config.MethodInvokingFactoryBean" depends-on="activitiBeanRegistry">
<property name="targetObject">
<ref bean="activitiBeanRegistry" />
</property>
<property name="targetMethod" value="put" />
<property name="arguments">
<list>
<value>sequenceUtil</value>
<ref bean="sequenceUtil" />
</list>
</property>
Open for extension closed for modification :)

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>
