Thanks for your help, Eric, my verification was wrong. Lew, rude as he was, was correct, it was a dumb mistake on my part. That being said, this is my first intro to SSCCE, a valuable concept.

I'm doing this...

         devObjectMap.put("ContentArea", new String[] {"All_Subject_Lines","Date_issue"});

but it's dropping the first entry. I verified in this case that the "DataExtension" entry was missing but the others were there. It's always the first entry I "put" that disappears. Here's the output of java -version...

     Your "verification" is wrong, with 99.44% probability. Could you

provide an SSCCE? Here's mine:

import java.util.Arrays;

import java.util.HashMap;

import java.util.Map;

public class Foo {

    public static void main(String[] unused) {

       HashMap<String, String[]> devObjectMap = new HashMap<String,

String[]>(5);

       devObjectMap.put("DataExtension", new String[]{"ADLN_Customer",

"ADLN_Story"});

       devObjectMap.put("Email", new String[]{"ADLN", "DRLN"});

       devObjectMap.put("EmailSendDefinition", new String[]{"ADLN",

"AILR"});

       devObjectMap.put("ImportDefinition", new

String[]{"ADLN_Customer", "ADLN_Story", "AILR_Customer"});

       devObjectMap.put("ContentArea", new String[]{"All_Subject_Lines",

"Date_issue"});

       for (Map.Entry<String, String[]> me : devObjectMap.entrySet()) {

          System.out.printf("\"%s\" -> %s%n", me.getKey(),

Arrays.toString(me.getValue()));

       }

    }

}

... and the output is:

run:

"ContentArea" -> [All_Subject_Lines, Date_issue]

"DataExtension" -> [ADLN_Customer, ADLN_Story]

"EmailSendDefinition" -> [ADLN, AILR]

"Email" -> [ADLN, DRLN]

"ImportDefinition" -> [ADLN_Customer, ADLN_Story, AILR_Customer]
