Hi

We have build an application, that build PDF Documents. With 4.6 all works fine, but when we change to 4.7 we get the folowing Exeption on the Save Method.

System.NullReferenceException: Object reference not set to an instance of an object.

Hi

No, because i have no idee wher the problem can be.

Hi,

I am afraid it's pretty difficult to figure out the actual cause of this problem until or unless we are able reproduce it at our end. From StackTrace I think the issue might be occurring when you are trying to use GraphInfo object while setting border information for the table but I am not entirely certain about this reason. However, it is even complicated to figure out the issue when the code used to work with Aspose.Pdf for .NET 4.6.0 and is crashing with Aspose.Pdf for .NET 4.7.0.

Can you please try generating a sample application that can help us in rectifying this problem. We are really sorry for your inconvenience.

Hi

Now i have a peace of Code:

Pdf pdf1 = new Pdf();

pdf1.IsBookmarked = true;

Section sec1 = pdf1.Sections.Add();

Table abstracttable = new Table();

abstracttable.ColumnWidths = "20% 80%";

//this line make Problems

abstracttable.Border = new BorderInfo((int)BorderSide.Bottom, 0.1F);

abstracttable.DefaultCellBorder = new BorderInfo((int)BorderSide.Bottom, 0.1F);

Row headerrow;

Cell titlecell;

Cell valuecell;

headerrow = abstracttable.Rows.Add();

titlecell = headerrow.Cells.Add("Document-ID");

//titlecell.DefaultCellTextInfo = textformatctitle;

valuecell = headerrow.Cells.Add("this is the TableText");

//valuecell.DefaultCellTextInfo = textformatcvalue;

sec1.Paragraphs.Add(abstracttable);

// Save the resultant PDF document

pdf1.Save(@"Z:/pdftest/TableBorderTestForAspose.pdf");

System.Diagnostics.Process.Start(@"Z:/pdftest/TableBorderTestForAspose.pdf");

Without the Line "

abstracttable.Border = new BorderInfo((int)BorderSide.Bottom, 0.1F);" all works fine.

Regards
