RE: [coldbox:18240] Using cfthread and wirebox

[br...@bradwood.com]

At first glance, is this a mapping issue?  Do you have a mapping for "com" or is it in the web root?  It's possible the thread is running out of the web context and doesn't know where the web root is.  I'm curious if an app mapping or server mapping would help ColdFusion find the components.

Thanks!

I have a scheduled task service component that is using threading to send out emails.  I am attempting to create a new instance of an object using wirebox, which works fine outside of the thread, but doesn't work inside the thread.  Any ideas?  This might be more of a question about threading that wirebox, but I thought this would be a good place to ask.  :)

component extends="com.acuity.services.tasks.LastDayOfMonthScheduledTask" accessors="true" singleton {

  property type="com.acuity.config.datasources.AcuityDatasource" name="acuityDatasource" inject="id:com.acuity.config.datasources.AcuityDatasource";
  property type="com.acuity.utils.AmazonSESUtil" name="amazonSESUtil" inject="id:com.acuity.utils.AmazonSESUtil";
  property type="com.acuity.emails.EmailFactory" name="emailFactory" inject="id:com.acuity.emails.EmailFactory";

  public void function run() IsExecuting output="false" {
  //execute batches in threads
    for (var i=1; i<=batches; i++) {
        thread action="run" name="#getName()##i#" i=i limit=limit {
            try {
               //this line below will not work when inside the thread execution context
               var email = application.wirebox.getInstance("com.acuity.emails.emails.tasks.NewsletterEmail");
               
               getLoggerService().debug("#getName()# new thread spawned: #getName()#-#i#");
 
               // email sending logic is here
           }
           catch (any exception) {
               getLoggerService().error(message="Error sending monthly newsletter.", exception=exception);
           }
        }
  }
}

When the call to getInstance is executed in the above code, an exception occurs stating that the instance cannot be found.  I have tried to replace the getInstance() with a standard createObject() function, and I am getting the same error.  Is this due to a limitation of threads in ColdFusion?

The logging is below that indicates the exception.
