Index out of range exception on TabStops getter for Paragraph with ListLevel

Aspose.Words Product Family

I'm getting the exception below when the the following code is executed. The code is in the process of creating an Aspose.Words document, and wants to clear out any existing tabstops that may have been inherited from the previously added Paragraph. Can you confirm this bug, and possibly also provide a workaround?

Thanks!

while (asposePara.ParagraphFormat.TabStops.Count > 0)
asposePara.ParagraphFormat.TabStops.RemoveByIndex(0);

Also, I put a try/catch around the above code as a workaround, but get a similar exception when I try to save the document:

Line 171: _toDoc.Save(stream, format);

Ah, I think I see my problem. I’m assigning a bogus ListLevel (-1) to the Paragraph earlier in the code. So it’s my fault, sorry. You may want to validate ListLevels when they’re assigned.
