Copy paragraph to another doc - lesson 2

I need to separate the task into 2 functions, because the second function will be used multiple times if processing book files.

In GetBiblioFromRTF paragraphs from document-1 are stored into a global array.

In PasteAtEnd the array-items are read and copied/pasted to the end of the active document-2..

If not closing the first document (outcomment line 18), the second document does not become active and hence the data is copied to its end.

However, if closing document-1 after filling the global array, the array is empty in each position and nothng is pasted (see the alerts).

#target FrameMaker
var gaBibliography= [];                           // keep bibliography lines from processed RTF
GetBiblioFromRTF ();

PasteAtEnd();

function GetBiblioFromRTF () {
  var nBib = 0, newDoc, pgf, pgf1, tRange;  newDoc = app.ActiveDoc;  pgf = newDoc.MainFlowInDoc.FirstTextFrameInFlow.FirstPgf;
// --- read the bibliography into the global array  while(pgf.ObjectValid()) {                      // until end of doc - take whole paragraphs    nBib += 1;                                    // count biblio paragraphs for later use in message    gaBibliography.push(pgf);                     // place the paragraph    pgf = pgf.NextPgfInFlow;
alert (GetText (gaBibliography[nBib-1], newDoc)); // => expected text  }  newDoc.Close (Constants.FF_CLOSE_MODIFIED);     // source document
} // --- end GetBiblioFromRTF

function PasteAtEnd () {
  var j, jMax, oDoc, lastPgf, pgf, textLoc, tRange;  jMax = gaBibliography.length;  if (app.ActiveDoc.ObjectValid()) {              // target document    oDoc = app.ActiveDoc;  } else {    Alert ("No active document!");    return;  }  lastPgf = oDoc.MainFlowInDoc.FirstTextFrameInFlow.LastPgf;  pgf = oDoc.NewSeriesPgf (lastPgf);              // Add a new paragraph at end of flow  tRange = new TextRange;  for (j = 0; j < jMax; j += 1) {    pgf1 = gaBibliography[j];                     // is object paragraph
alert (GetText (gaBibliography[j], oDoc));        // => nothing    tRange.beg.obj = pgf1;                        // select it    tRange.beg.offset = 0;    tRange.end.obj = pgf1;    tRange.end.offset = Constants.FV_OBJ_END_OFFSET;    oDoc.TextSelection = tRange;    PushClipboard ();    oDoc.Copy (0);                                // copy selection to clipboard not interactive    textLoc = new TextLoc (pgf, 0);     textRange = new TextRange (textLoc, textLoc);    oDoc.TextSelection = textRange;               // set TextSelection to insertion point     oDoc.Paste ();                                // "replace" TextSelection    PopClipboard ();  }
}

function GetText (textObj, doc) {
  var text = "", textItems;  if (textObj.constructor.name !== "TextRange") { // Get a list of the strings in the text object or text range    var textItems = textObj.GetText(Constants.FTI_String);  } else {    textItems = doc.GetTextForRange(textObj, Constants.FTI_String);  }  for (var i = 0; i < textItems.len; i += 1) {    // Concatenate the strings    text += (textItems[i].sdata);  }  return text;                                    // Return the text
} // --- end GetText

There seems to be a 'hidden connection' between the array items and the first document, which of course will be broken, if this is closed. I thought to have all the stuff in the array which is needed for the second step.

Can anybody give me a hint how get this running correctly?
