Help required - calling Minilang Experts

Hello MiniLang Experts,


I am migrating the checkStatusCustRequest service to Groovy (OFBIZ-11692 <https://issues.apache.org/jira/browse/OFBIZ-11692>), part of our May CommunityDays scope and sprint.
In the finalization I now notice that the original Minilang service „checkStatusCustRequest“ is called by two other services as an inline call-simple-method statement:

Source is /applications/order/minilang/request/CustRequestServices.xml:

#121
Was:
<simple-method method-name="updateCustRequest" short-description="Update Customer Request">
    <call-simple-method method-name="checkStatusCustRequest"/>
    <set field="oldStatusId" from-field="custRequest.statusId“/>

Changed to:
<simple-method method-name="updateCustRequest" short-description="Update Customer Request">
    <set field="crqCheck.custRequestId" from-field="parameters.custRequestId"/>
    <set field="crqCheck.locale" from-field="parameters.locale"/>
    <set field="crqCheck.userLogin" from-field="parameters.userLogin"/>
    <call-service service-name="checkStatusCustRequest" in-map-name="crqCheck">
        <results-to-map map-name="crqCheckResult"/>
    </call-service>
    <set field="oldStatusId" from-field="custRequest.statusId"/>

And the second service in the same minilang file

#237
Was:
<simple-method method-name="createCustRequestItemNote" short-description="Create Customer RequestItem Note">
    <call-simple-method method-name="checkStatusCustRequest"/>        
    <make-value entity-name="CustRequestItemNote" value-field="newEntity"/>

Changed to:
<simple-method method-name="createCustRequestItemNote" short-description="Create Customer RequestItem Note">
    <set from-field="parameters.custRequestId" field="crqCheck.custRequestId"/>
    <set from-field="parameters.locale" field="crqCheck.locale"/>
    <set from-field="parameters.userLogin" field="crqCheck.userLogin"/>
    <call-service service-name="checkStatusCustRequest" in-map-name="crqCheck"/>
    <make-value entity-name="CustRequestItemNote" value-field="newEntity"/>

While the latter passes testing now, the first does not, complaining that:

      <testcase classname="org.apache.ofbiz.testtools.SimpleMethodTest" name="custrequest-tests.testCreateNewRequest" time="0.101">
          <failure message="ERROR: Could not complete the update a request [file:/Users/carsten/github/ofbiz-framework/applications/order/minilang/test/CustRequestTests.xml#inlineUpdateRequest] process [problem invoking the [updateCustRequest] service with the map named [updateRequestMap] containing [{userLogin=[GenericEntity:UserLogin][createdStamp,2020-05-25 09:59:39.293(java.sql.Timestamp)][createdTxStamp,2020-05-25 09:59:39.167(java.sql.Timestamp)][currentPassword,null()][disabledBy,null()][disabledDateTime,null()][enabled,N(java.lang.String)][externalAuthId,null()][hasLoggedOut,null()][isSystem,Y(java.lang.String)][lastCurrencyUom,null()][lastLocale,null()][lastTimeZone,null()][lastUpdatedStamp,2020-05-25 09:59:41.161(java.sql.Timestamp)][lastUpdatedTxStamp,2020-05-25 09:59:41.121(java.sql.Timestamp)][partyId,system(java.lang.String)][passwordHint,null()][requirePasswordChange,null()][successiveFailedLogins,null()][userLdapDn,null()][userLoginId,system(java.lang.String)], custRequestName=New Test Customer request, fromPartyId=admin, statusId=CRQ_ACCEPTED, custRequestId=10530, custRequestTypeId=RF_INFO, priority=2, locale=en}]: Outgoing result (in runSync : updateCustRequest) does not match expected requirements (The following required parameter is missing: [OUT] [updateCustRequest.oldStatusId])]" type="junit.framework.AssertionFailedError">junit.framework.AssertionFailedError: ERROR: Could not complete the update a request [file:/Users/carsten/github/ofbiz-framework/applications/order/minilang/test/CustRequestTests.xml#inlineUpdateRequest] process [problem invoking the [updateCustRequest] service with the map named [updateRequestMap] containing [{userLogin=[GenericEntity:UserLogin][createdStamp,2020-05-25 09:59:39.293(java.sql.Timestamp)][createdTxStamp,2020-05-25 09:59:39.167(java.sql.Timestamp)][currentPassword,null()][disabledBy,null()][disabledDateTime,null()][enabled,N(java.lang.String)][externalAuthId,null()][hasLoggedOut,null()][isSystem,Y(java.lang.String)][lastCurrencyUom,null()][lastLocale,null()][lastTimeZone,null()][lastUpdatedStamp,2020-05-25 09:59:41.161(java.sql.Timestamp)][lastUpdatedTxStamp,2020-05-25 09:59:41.121(java.sql.Timestamp)][partyId,system(java.lang.String)][passwordHint,null()][requirePasswordChange,null()][successiveFailedLogins,null()][userLdapDn,null()][userLoginId,system(java.lang.String)], custRequestName=New Test Customer request, fromPartyId=admin, statusId=CRQ_ACCEPTED, custRequestId=10530, custRequestTypeId=RF_INFO, priority=2, locale=en}]: Outgoing result (in runSync : updateCustRequest) does not match expected requirements (The following required parameter is missing: [OUT] [updateCustRequest.oldStatusId])]

   at org.apache.ofbiz.base.start.Start.main(Start.java:90)
          </failure>
So something in my checkStatusCustRequest call is not digesting the response from the sub-service properly I suspect as the test complains that the subsequent line originally in line #123 which maps the oldStatusId is not executed as that field is missing in the response.

Now I am not an expert at all with these cross-service calls, what would you suggest here?

Also, a tactical option could be to extend the story to port all three to Groovy knowing that the other two are not called as nested call-simple-method statements by other services, but always as call-service statements which assumedly makes it fairly easy to port (but will cause scope slippage).

Thanks for any views and hints.
Warm regards


Carsten

Hi Scott,


Thanks for your comment. I understand … and I don’t.
See, this is the message sequence in the two cases:

Case 1
updateCustRequest
==> calls checkStatusCustRequest
   (Will fail the check if not in an in-progress status)
<== returns to calling simple service
… do the updateCustRequest stuff

Test result: FAIL.


Case 2
createCustRequestItemNote
==> calls checkStatusCustRequest
   (Will fail the check if not in an in-progress status)
<== returns to calling simple service
… create the CustRequestItemNote

Test result: PASS.


The checkStatusCustRequest is a read-only method, only reason to run it is a failure message being raised when the referenced custRequest does not have an allowed status. Yet, it will in the background already read the custRequest object from the Entity store.

I tried:
- putting the copy-step first in the method before calling the StatusCheck (test expects the updateCustRequest.oldStatusId
 to be returned in the OUT map
- renaming the local variable in the StatusCheck method to avoid interference with the calling method’s context
- not returning a success message from the StatusCheck method to avoid any „pollution“ of the calling method’s context

Still I see the same error in all these attempts as mentioned below, namely that test expects the presence updateCustReuqest.oldStatusId as a return value of the updateCustRequest method. I do hence not seem to get it right. Any ideas?

Warm regards


Carsten

Hi Carsten,

call-simple-method executes in the same manner as if you copied the code
from the method being called directly into your code, i.e. it has the same
variable scope as the method it's being called from.  So the "custRequest"
variable from checkStatusCustRequest was available to updateCustRequest.
Now that the implementation is a service, you'd need to explicitly return
that value from the service in order to be able to use it.

Regards
Scott
