Hi all,Please I need help with the problem. :cry: My service task is this:
<serviceTask id="Service" activiti:class="engine.bpmn.tasks.Service">
<extensionElements>
<activiti:field name="testService" expression="#{testService}" />
<activiti:field name="parameters" expression="customer" />
<activiti:field name="withoutException" expression="noException" />
<activiti:field name="withException" expression="exception" />
</extensionElements>
</serviceTask>
And in Spring i have:
<bean id="testService" class="engine.common.cannonical.testService">
<property name="ServiceManager" ref="ServiceManagerListener" />
</bean>
<bean id="processEngineConfiguration" class="org.activiti.spring.SpringProcessEngineConfiguration">
<property name="dataSource" ref="dataSource" />
<property name="transactionManager" ref="transactionManager" />
<property name="databaseSchemaUpdate" value="true" />
<property name="mailServerHost" value="localhost" />
<property name="mailServerPort" value="4025" />
<property name="jobExecutorActivate" value="false" />
<property name="processEngineName" value="ManagerBpmEngine" />
<property name="dbCycleUsed" value="true" />
<property name="beans">
<map>
<entry key="testService" value-ref="testService" />
</map>
</property>
</bean>
When I running the following error is shown:
Incompatible type set on field declaration 'testService' for class engine.bpmn.tasks.Service. Declared value has type org.activiti.engine.impl.el.JuelExpression, while expecting org.activiti.engine.delegate.Expression
any idea?
ops:
