EDA Event Source with strategy "delta"

Hi,

I’ve defined an event source with strategy “delta” and identifier and command attribute. But my mashups delivers no data (without exception). Just an empty result.

If I’m using “Buffer” (not Delta) everything works fine!

Event Source definition:

Strategy: DELTA
Event ID attribute: uuid
Command attribute: commandDelta
Capacity: 10
Memory Model: Internal
Throttling: 500
Throttling Type: Milliseconds

We get many events in our UM contains uuid and commandDelta attributes. XML:

<?xml version='1.0' encoding='UTF-8'?>

<p1:VipFan xmlns:p1=“http://namespaces.softwareag.com/EDA/Kairos”>
p1:uuidac576269-ec4b-4b42-bc29-3a03078d31ce</p1:uuid>
p1:nameHelmut</p1:name>
p1:moodLevel16</p1:moodLevel>
p1:blockW</p1:block>
p1:commandDeltaInsert</p1:commandDelta>
</p1:VipFan>

Now our Mashup delivers no data:

If I’m using “Buffer” (not Delta) everything works fine!

What is the problem?
