<set /> for eeca and seca

[cqnunez]

We have added "updatedByUserLogin" and "updateDate" as fields for the orderHeader entity.

We defined an eeca

<eca entity="OrderStatus" operation="create" event="return">
    <condition field-name="orderId" operator="is-not-empty" />
    <condition field-name="orderItemSeqId" operator="is-empty" />
    <set field-name="updatedByUserLogin" env-name="statusUserLogin" />
    <set field-name="updateDate" env-name="statusDatetime"/>
    <action service="updateOrderHeader" mode="sync" />
  </eca>

and got the ff error msg

Error in Service [changeOrderStatus]: ERROR : Could not change order status (The current transaction is marked for rollback, not beginning a new transaction and aborting current operation; the rollbackOnly was caused by: Service [changeOrderStatus] threw an unexpected exception/errororg.ofbiz.service.GenericServiceException: Service [changeOrderStatus] target threw an unexpected exception (java.sql.Timestamp) (Service [changeOrderStatus] target threw an unexpected exception (java.sql.Timestamp))).

The service is called when <set field-name="updateDate" env-name="statusDatetime"/> is removed.

Does the <set /> definition for eeca and seca only accept String values from the parameter?
