Hello,
Maybe I wrongly understand your problem but, what if when the call is not
made, you just send an dummy (empty?) payload with the same structure you
would retrieve if the call was made? I suppose you are using the filter
mediator for your "if" condition?
For example:
<clone>
<target>
<sequence>
if condition
use send/call mediator to call the endpoint
else
payload factory mediator invokation to construct a dummy
payload
</sequence>
</target>
</clone>
And when you specifiy send/call mediator, do you mean that you have tried
with both call and send mediators and it has the same result?
Regards,
Thomas
