When there is an abstractNum defined with the same abstractNumId in word\glossary\numbering.xml and in the word\numbering.xml, a "System.ArgumentException: An item with the same key has already been added." exception is thrown.

In other cases, the import overwrites the styles from the main document part with the ones defined in the glossary or fails to import different parts of the content. 

Reading a password protected archive by passing a wrong password doesn't notify the user that the password is wrong. Accessing one of the entries in the archive throws a generic "Invalid data" exception.

Steps to reproduce:
1. Create a zip file with password.
2. Open the same archive with the API passing wrong password and then try to one of the entries.
Observed: InvalidDataException is thrown when trying to read one of the entries in the archive.
Expected: The exception should be more meaningful and if possible occur when reading the archive. There should be API allowing to check if the password is correct.

Wrong text appearance when editing field because of the wrong FieldFlag ("Ff") exported.

When creating a GradientStop, an alpha channel of the color could be applied. However, this setting is not respected it the result document and the gradient is with full opacity.

Steps to reproduce:
1. Create a gradient with an alpha channel:

RadFixedDocument document = new RadFixedDocument();
RadFixedPage page = document.Pages.AddPage();
FixedContentEditor containerEditor = new FixedContentEditor(page);

LinearGradient linearGradient = new LinearGradient(new Point(0, 0), new Point(30, 30));
linearGradient.GradientStops.Add(new GradientStop(new RgbColor(10, 0, 207, 0), 0));
linearGradient.GradientStops.Add(new GradientStop(new RgbColor(10, 0, 102, 204), 1));

containerEditor.GraphicProperties.FillColor = linearGradient;
containerEditor.DrawRectangle(new Rect(10, 10, 48, 29));

2. Export the document to PDF

Observed: The alpha channel is not respected and the gradient is with full opacity

CellSelection.SetValue method causes memory leak of CellReferenceRangeExpression objects in some cases when cell value is referenced by formulas. The memory leak is small, but the remaining CellReferenceRangeExpression continue to listen to some events, causing performance issues when their number become large - the time to set the value increases with each set.

In scenarios when center and right tabs are used for aligning the paragraph content to both left and right the text content in the exported PDF is not positioned as expected.

The issue may be reproduced by opening the attached PDF in Adobe Reader. Although the viewer initially shows the characters correctly, when you start typing in the TextBox, the umlaut/diacritics characters get corrupted. In other PDF viewers, the umlaut characters are handled correctly, so the issue seems to related to concrete Adobe Reader encoding handling implementation. The diacritic characters are handled incorrectly in other viewers as well (e.g. Chrome).

LineInfo objects are not cleared when there are tables in the document being exported to PDF which leads to OutOfMemoryException.

The table styles are not imported correctly from HTML. The back color is not respected. The column width is incorrect. The font size is different.

The executing of the PostScriptReader`s Read method takes a lot of time when iterating content streams with many Path geometries.

Removing/adding rows/columns inside a worksheet requires all the data after them to be translated according to the change. This operation is slow and affects editing performance.

When the indentation of a paragraph, which is located in a list, is locally set, its indentation is not property exported to RTF.

Is there a way to prevent font embedding in the RadFlow methodology or is utilizing RadFixed the only way to have a reasonably sized PDF document?

When merging documents using the RadFixedDocument`s Merge() method the fonts are not successfully merged which leads to missing characters in the produced document.

Workaround: replace the font with a full font (not a subset) before exporting to a PDF file:

byte[] data = File.ReadAllBytes("verdana.ttf");
FontFamily verdanaRegularFontFamily = new FontFamily("Verdana");
FontsRepository.RegisterFont(verdanaRegularFontFamily, FontStyles.Normal, FontWeights.Normal, data);
FontsRepository.TryCreateFont(verdanaRegularFontFamily, out FontBase verdanaRegularFont);

foreach (RadFixedPage page in mergedDocument.Pages)
{
	foreach (TextFragment textFragment in page.Content.Where(c => c is TextFragment).Cast<TextFragment>())
	{
		textFragment.Font = verdanaRegularFont;
	}
}

Watermark transparency is not imported correctly

The CombTextBoxField text alignment is wrong when a file is imported and then exported.

After the import-export of a specific document, the paths are thinner and the corners of the path figure are not rounded:

 

Exception when there are merge fields in the header/footer and one performs mail merge: 

Unable to cast object of type 'Telerik.Windows.Documents.Flow.Model.Header' to type 'Telerik.Windows.Documents.Flow.Model.BlockBase

Currently, the Multilevel Numbering list is supported but when nesting one-level Numberings this results in wrongly exported to HTML multilevel list.
