Enumerating EOs in a new thread


  • Subject: Enumerating EOs in a new thread

I'm attempting to pass an enumeration of eo's into the background in a separate thread thus prevent it delaying unnecessarily a response. After a quick attempt I got the error below. Looks like I'm doing something EOF is not expecting here but my knowledge isn't deep enough to understand what that is. I've encountered this before when working with EO's in separate threads, are there some rules to follow when doing so?


Exception in thread "Thread-1" java.lang.NullPointerException
at com.webobjects.eocontrol.EOFaultHandler._lockResources (EOFaultHandler.java:265)
at com.webobjects.eoaccess.EOAccessArrayFaultHandler.completeInitialization OfObject(EOAccessArrayFaultHandler.java:64)
at com.webobjects.eocontrol._EOCheapCopyMutableArray.willRead (_EOCheapCopyMutableArray.java:38)
at com.webobjects.eocontrol._EOCheapCopyMutableArray.objectEnumerator (_EOCheapCopyMutableArray.java:102)
at com.kisky.treasuremytext.helpers.ActionHelper $PerformMultipleActionsTask.run(ActionHelper.java:375)


To understand more what I'm trying to do here to see if there is a better way maybe - I'm enumerating through a large number of EOs checking some conditions on each before deciding if I want to perform some arbitrary action (in this case send an email), I do not need to make any changes to the EOs themselves.

Thanks
