extending an eca

[chris snow]

Is it possible to extend an eca?  For example, when an order is
completed, I would like to call another service.  There is already an
OOTB eca:

    <eca service="changeOrderItemStatus" event="commit">
        <condition field-name="statusId" operator="equals"
value="ITEM_COMPLETED"/>
        <action service="checkOrderItemStatus" mode="sync"/>
    </eca>

I can't see a way to extend this, should I just place a duplicate eca
definition in mycomponent, e.g.

    <eca service="changeOrderItemStatus" event="commit">
        <condition field-name="statusId" operator="equals"
value="ITEM_COMPLETED"/>
        <action service="checkOrderItemStatus" mode="sync"/>
        <action service="myCustomerService" mode="sync"/>
    </eca>

Will this duplicate definition override the OOTB one?

Many thanks,

Chris

don't believe so
just remove the
           <action service="checkOrderItemStatus" mode="sync"/>
from yours
both will fire.
Note: unless I want to change based on commit I use one of the other
triggers that fit my service. they all effect the same transaction.

oops meant event instead of trigger

Hi BJ, I don't understand your last line - can you please elaborate?

I would like checkOrderItemStatus and myCustomerService to be part of
the same transaction - i.e. both are successful or get rolled back.

[BJ Freeman]

sorry about that
was thinking same service and wrote same transaction.
as far as I know you do not replace the other eca so it will be
processed then yours will be.
