The latest svn still has this as an async method but it only works for me when it's mode is sync.  is this a bug?

changed from async to sync and now it works.


<eca entity="InventoryItem" operation="create-store" event="return">
        <condition field-name="productId" operator="is-not-empty"/>
        <condition field-name="availableToPromiseTotal" operator="is-not-empty"/>
        <condition field-name="availableToPromiseTotal" operator="less-equals" value="0" type="Double"/>
        <action service="checkProductInventoryDiscontinuation" mode="sync"/>
    </eca>

Actually this service is part of a recent ofbiz checkout. I am using batch  ofbiz.jar -install -file=......  to load a bunch of  InventoryItem records.
It does not look like the service is getting executed since the service manager is failing to start it. or so it seems.
yes this is a simple service.

the try catch was if you have java type service.
if you have a simple service you may have optional set as false for 
something that may not have data all the time.

Ran into this when was doing something similar, but the customer 
sometimes did not fill all the variables.

I would say it is the service

Service [checkProductInventoryDiscontinuation] threw an unexpected
exception/error
Exception: java.lang.NullPointerException
Message: null
looks like a custom service. maybe rap your functions with try and catch.

hi,

I am trying to import an InventoryItem record and getting null pointer 
when trying to run checkProductInventoryDiscontinuation.

The error occurs in GenericAsyncEngine.java in runAsync at  
dispatcher.getJobManager().runJob(job);  it seems getJobManager is 
returning null.

I added some extra debug info to help me narrow it down.
