Yes thats exactly how it behaves... though I am not inserting text,
changing formatting
or applying numbering, i am merely building a hierachy of the document
structure in terms of the numbering level (everything is "read"
activity ) - and storing this hierarchy into a vector that in turn
refreshes a JList list box....... see the brief extract of code below

Sorry for the misleading subject.. it was a bit late in the night.. i
thought it was
something to do the view cursor :-)

Is there anyway i can suppress the automatic scrolling back behaviour... ?
it seems like a usability issue to me..., maybe even a bug, since I am
not really
writing anything into the document.
The list box refresh code runs in a swing timer class that runs
every 10 seconds...
At the moment its quite disconcerting for the user when the document
seems to jump and scroll randomly... when all they are doing is
scrolling through the document using the mouse....(either using the
mouse wheel or by dragging the scroll bar...)

[1] - paragraph enumeration code :
while (paraEnum.hasMoreElements()) {
.....
objNextElement = paraEnum.nextElement();
//get service info
xInfo = UnoRuntime.queryInterface(XServiceInfo.class, objNextElement);
if (xInfo.supportsService("com.sun.star.text.Paragraph")) {
XPropertySet xSet = (XPropertySet)
UnoRuntime.queryInterface(XPropertySet.class, xInfo);
nLevel =
AnyConverter.toShort(xSet.getPropertyValue("ParaChapterNumberingLevel"));
if (nLevel >= 0 ){
....
XTextContent xContent = ooDocument.getTextContent(objNextElement);
XTextRange aTextRange = xContent.getAnchor();
String strHeading = aTextRange.getString();
//this is the structure added to the vector which
refreshes the JList box...
//the object also stores the text range of the heading....
DocStructureElement element = new
DocStructureElement(strHeading, nLevel, aTextRange );
vectorDocumentHeadings.addElement(element);
}
}
}
