I'm trying to merge several files generated at runtime using SyncFusion 5.1.0.54

but i'm getting the following exception:

?ex
{System.NullReferenceException}
[System.NullReferenceException]: {System.NullReferenceException}
HelpLink: Nothing
InnerException: Nothing
Message: "A referência de objecto não foi definida como uma instância de um objecto."

at Syncfusion.DocIO.DLS.WSection.CloneImpl(IDocument document)
at Syncfusion.DLS.Section.Clone(IDocument document)


the exception ocurres with the following code:

For Each MySection In aSyncDocument.Document.Sections
DirectCast(Me.Document.Sections, Syncfusion.DLS.ISectionCollection).Add(MySection.Clone(Me.Document))
Me.Document.LastSection.BreakCode = MySection.BreakCode
Next

the content of aSyncDocument.Document is the attachment. i got it using aSyncDocument.Document.Save method.

aSyncDocument.Document is the SyncFusion.DocIO.DLS.WordDocument.

the Me.Document is the final merger document.

Hi Lima ,

Thank you for your interest in Essential DocIO,

I was unable to reproduce the issue. I tested this issue with CloningAndMerging Sample that is available along with the installs with the document provided to us. The sample can be found at the following place.

C:\Documents and Settings\{user}\My Documents\Syncfusion\EssentialStudio\5.1.0.54\Windows\DocIO.Windows\Samples\2.0\Advanced Features\CloningandMerging\CS

Can you provide us with the sample application, documents with which your are able to reproduce the issue.Kindly take a look and us know if you have any other questions.

Regards,
Ajish.

I attach a sample application.
The problem comes on the line:

DirectCast(Me.Document.Sections, Syncfusion.DLS.ISectionCollection).Add(MySection.Clone(Me.Document))

a think it can be related with the insert of the image at runtime.
if I put the line
MyTemDocument.Save("C:\test\result" & System.Guid.NewGuid.ToString & ".doc", FormatType.Doc)
before the line
AppendDocument(MyTemDocument)

it saves all the document with success.
