Hi Aspose,

The issue is appeared in 18.6 version.

Document clone method doesn’t work correctly.
Issue: the cloned document is linked with the original document.

Source code:

var document = new Document();

var builder = new DocumentBuilder(document);

for (var i = 0; i < 10; i++)
{
    builder.StartBookmark(i.ToString());
    builder.Write(i.ToString());
    builder.EndBookmark(i.ToString());
    builder.Writeln();
}

builder.Writeln();
builder.Writeln("Bookmarks count | original: " + document.Range.Bookmarks.Count);

var count = document.Range.Bookmarks.Count;

var documentClone = document.Clone();
documentClone.Range.Bookmarks.Clear();

builder.Writeln("Bookmarks count | original + clearing the clone: " + document.Range.Bookmarks.Count);

var builderClone = new DocumentBuilder(documentClone);
for (var i = 0; i < 10; i++)
{
    builderClone.StartBookmark(i.ToString());
    builderClone.Write(i.ToString());
    builderClone.EndBookmark(i.ToString());
    builderClone.Writeln();
}

builder.Write("Bookmarks count | clone: " + documentClone.Range.Bookmarks.Count);

document.Save("C:\\test.docx", SaveFormat.Docx);

Result:

Bookmarks count | original: 10
Bookmarks count | original + clearing the clone: 0
Bookmarks count | clone: 20

Thanks.

@spectr100,

Thanks for your inquiry. Please call Document.UpdatePageLayout method as shown below to get the desired output.

var document = new Document();

var builder = new DocumentBuilder(document);

for (var i = 0; i < 10; i++)
{
    builder.StartBookmark(i.ToString());
    builder.Write(i.ToString());
    builder.EndBookmark(i.ToString());
    builder.Writeln();
}

builder.Writeln();
builder.Writeln("Bookmarks count | original: " + document.Range.Bookmarks.Count);

var count = document.Range.Bookmarks.Count;

document.UpdatePageLayout();

var documentClone = document.Clone();
documentClone.Range.Bookmarks.Clear();

builder.Writeln("Bookmarks count | original + clearing the clone: " + document.Range.Bookmarks.Count);

var builderClone = new DocumentBuilder(documentClone);
for (var i = 0; i < 10; i++)
{
    builderClone.StartBookmark(i.ToString());
    builderClone.Write(i.ToString());
    builderClone.EndBookmark(i.ToString());
    builderClone.Writeln();
}

documentClone.UpdatePageLayout();
builder.Write("Bookmarks count | clone: " + documentClone.Range.Bookmarks.Count);

document.Save(MyDir + "18.6.docx", SaveFormat.Docx);

Hi Tahir,

This workaround doesn’t work:

Bookmarks count | original: 10
Bookmarks count | original + clearing the clone: 0
Bookmarks count | clone: 10

Expected result:

Bookmarks count | original: 10
Bookmarks count | original + clearing the clone: 10
Bookmarks count | clone: 10

Also on the real project UpdatePageLayout() doesn’t help at all.

18.5 version works fine.
