Q I'm doing some work merging text into PDF,
Could you please explain why I got the following exception:
Exception: Message: Text objects can't nest
-------
A: PDF format does not allow nesting text blocks. The error means that
you are creating one text block (builder.CreateTextBegin()) within
another. This is sometimes indication that you forgot to close a
previous text block (e.e. using writer.WriteElement
(builder.CreateTextBegin())) .
