Splitter Issue

[jamesclinton]

Split result not being picked up by Aggregator listening to splitter output channel.

I have a service-activator which returns a List<MyObject>.

This list is picked up by a splitter. The splitter just returns the input.

The split output channel is input to an aggregator which has a custom correlation and release strategy.

For some reason if I include the splitter the release strategy is never entered. I can write some extra code to get round this in the release strategy but would prefer to use the splitter.

As far as I understand the splitter should result in 3 messages and 3 isComplete calls on the release strategy, but none occur.

1 does occur if the splitter is removed but the message payload is a List of 3 items...I have other sources which determine the complete state so would prefer the payload type to be the same.

public List<MyObject> split(List<MyObject> list) 
    {
        return list;
    }

<si:channel id="in"/>
<si:channel id="out"/>
    
    <si:splitter
        ref="sb"
        method="split"
        input-channel="in"
        output-channel="out"/>
        
    <bean
        id="sb"
        class="Splitter">
    </bean>

<si:aggregator 
        ... 
        input-channel="out"
        ...
 />

Can you show the configuration of the splitter element?

By the way, if you are just expecting a Collection or array, you don't need a method to be invoked by the splitter, you can just use <splitter> without any ref/method or expression attributes, and it will handle the Collection or array by default.

Hi Mark
Some config added.
Will try your suggestion.

Some further information.

The correlation strategy is fired 3 times as expected, but no hits on the release strategy.
