I'd like to merge multiple DOCs. The first DOC to merge will do like expected. But if I try to merge the second, I get this exception:

[NullReferenceException: Objekt not set to an instance of an object.]
Syncfusion.DocIO.DLS.WParagraphStyle.CloneListRelationsTo(WordDocument doc)
Syncfusion.DocIO.DLS.WParagraph.CloneStyleTo(WordDocument doc)
Syncfusion.DocIO.DLS.WParagraph.CloneRelationsTo(WordDocument doc)
Syncfusion.DocIO.DLS.WTextBody.CloneRelationsTo(WordDocument doc)
Syncfusion.DocIO.DLS.WSection.CloneRelationsTo(WordDocument doc)
Syncfusion.DocIO.DLS.EntityCollection.OnInsert(Int32 index, Entity entity)
Syncfusion.DocIO.DLS.EntityCollection.CloneTo(EntityCollection destColl)
Syncfusion.DocIO.DLS.WordDocument.ImportContent(IWordDocument doc, Boolean importStyles)

My source code is taken from your samples. Here it is.

IWordDocument doc = new WordDocument();
doc = CreateFirstMergeDoc();
foreach (IWSection sec in doc.Sections)
baseDoc.LastSection.BreakCode = sec.BreakCode;
doc = CreateSecondMergeDoc();
foreach (IWSection sec in doc.Sections)
baseDoc.Sections.Add(sec.Clone()); <-- here rises the exception
baseDoc.LastSection.BreakCode = sec.BreakCode;

I load DOT templates in every Create... method.

What is wrong?
