Re: Association between ToC index object and its paragraph content

Michael, I the case you describe would I not see the same UNO object address for the same paragraph 
in the document? But iterating over the ToC’s paragraphs as described previously in this thread, I 
get for the index view:

    pyuno object (com.sun.star.text.XTextContent)0x7feddb8d2638{implementationName=SwXParagraph, … }

and then for the global document view:

    pyuno object (com.sun.star.text.XTextContent)0x7fedd9f5f598{implementationName=SwXParagraph, … }

for the same first entry paragraph in the ToC. In fact, if I instantiate the ToC’s text range three 
times, then I get three different objects for the first paragraph:

    pyuno object (com.sun.star.text.XTextContent)0x7fc6b1d41188
    pyuno object (com.sun.star.text.XTextContent)0x7fc6b1e66968
    pyuno object (com.sun.star.text.XTextContent)0x7fc6b430e288

Do paragraphs have another unique identifier that associates these different instances as objects 
representing the same document paragraph?
