    Let's start here.  Due to specific constraints of my environment I cannot connect directly to the database.  In leu of these I am using an additional layer via WebServices.

    I have 3 methods in my webservice...

    GetPartNumbers_IDEnumerator()
    GetPart_SpecificFinder()
    GetParts (Finder)

    As far as the WebService goes, GetPartNumbers_IDEnumerator() returns an ArrayOfString(Collection) with string elements containing only the ID's.  See below
    <?xml version="1.0" encoding="utf-8"?>
<ArrayOfString xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://intranet1/WebServices/">
  <string>01210801         00 </string>
  <string>02050902         00 </string>
  <string>02050903         00 </string>
  <string>100014           03 </string>
  <string>100020           03 </string>
</ArrayOfString>

    GetPart_SpecificFinder() returns below...
    <GSSPart>
  <PartNumber>102233           00</PartNumber>
  <PartDescription>WELDED REAR SHELF ASSY 150    </PartDescription>
  <Exists>true</Exists>
</GSSPart>

    GetParts() returns...
    <ArrayOfGSSPart>
  <GSSPart>
  <PartNumber>100014           03 </PartNumber>
  <PartDescription>CLIP                          </PartDescription>
  <Exists>true</Exists>
</GSSPart>
<GSSPart>
  <PartNumber>100020           03 </PartNumber>
  <PartDescription>BOTTOM TRANSFER PLATE (BE)    </PartDescription>
  <Exists>true</Exists>
</GSSPart>
</ArrayOfGSSPart>


    Using ApplicationDefinitionDesigner, when Executing the IDEnumerator method, I get the error,
    "Index was out of range.  Must be non-negative and less than the size of the collection.  Parameter name: index."

    I know what the error means, but I don't know why I'm getting it.  I'm assuming it has something to do with my ADF, but I don't know what.


    However, the Finder and Specific Finder methods work fine.

    Any ideas welcome.  Including my ADF.

    Istead of something like this

    <string>01210801         00 </string>
      <string>02050902         00 </string>
      <string>02050903         00 </string>
      <string>100014           03 </string>
      <string>100020           03 </string>

    Try returning something like
    <PartNumber>01210801         00 </PartNumber>
      <PartNumber>02050902         00 </PartNumber>
      <PartNumber>02050903         00 </PartNumber>
      <PartNumber>100014           03 </PartNumber>
      <PartNumber>100020           03 </PartNumber>

    Just a suggestion, you can try and see if it helps.

    Cheers
