CompositeItemWriter not registering StepExecutionListener

[farooqui]

Hi All,

I may be doing this incorrectly; but it seems CompositeItemWriter does not register the StepExecutionListener correctly if one it's delegate ItemWriter implements the StepExecutionListener interface.

Here is the Job:

	<batch:job id="testJob">
		<batch:step id="step1">
			<batch:tasklet>
				<batch:chunk commit-interval="2" >
					<batch:reader>
						<ref bean="itemReader"/>
					</batch:reader>
					<batch:processor>
						<ref bean="itemProcessor"/>
					</batch:processor>
					<batch:writer>
						<ref bean="compositeWriter"/>
					</batch:writer>
					<batch:streams>
						<batch:stream ref="documentAccumulatorWriter"/>
					</batch:streams>
				</batch:chunk>
			</batch:tasklet>
		</batch:step>
		<batch:listeners>
			<batch:listener ref="documentAccumulatorWriter"/>
		</batch:listeners>
	</batch:job>

Here is the Composite writer definition

	<bean id="compositeWriter" class="org.springframework.batch.item.support.CompositeItemWriter">
		<property name="delegates">
			<list>
				<ref bean="documentAccumulatorWriter"/>
			</list>
		</property>
	</bean>

Here is the ItemListener Class Definition

public class DocumentAccumelatorItemWriter implements ItemWriter<ClaimPrintBatch>, StepExecutionListener, JobExecutionListener, ItemStream{

The JobExecutionListener and ItemStream are working, the problem is just with StepExecutionListener.

At the moment I am just playing around with a prototype; but was really hoping to use the CompositeWriter. Please let me know if it's something I am doing wrong or if there is a way to get around this issue. Thank you.

Nothing wrong here. The composite writer should not register listeners because you might not want them to be registered (also because it is a cyclic dependency in the source). You have to register all listeners and streams explictly if they aren't the "main" reader, writer or processor in a step.
