Hi,

I had a requirement where I had to make a deep copy of a textflow,I was under an impression that it would make a copy of this textflow.

Yes,it did make a copy of the textflow a new instance but the paragraph elements under this textflow were referencing to the same tabstop arrays which the original textflow was referencing.

Now is this a bug or is it supposed to be like this only.

It is to save memory. 

The TabStops array and the actual TabStop object instances that are members of the array should be treated as read-only in the below cases.

1) once it is set into a TextLayoutFormat

2) when it is read from a TextLayoutFormat

3) when it is read from an implementer of ITextLayoutFormat

So, in my case I will have to use the utility of copying the TabStops array and the new (copied) textflow should reference it instead of the actual arrays.
