Exception during GetFirstPara method call


I have a following vbs script which I want to use with LibreOffice 4.4.1:

Set objServiceManager= WScript.CreateObject("com.sun.star.ServiceManager")
Set objDesktop= objServiceManager.createInstance("com.sun.star.frame.Desktop")

Set objDocument = objDesktop.getCurrentComponent

Set paraIterator = objDocument.getFlatParagraphIterator(1, False)
Set oPara = paraIterator.GetFirstPara ' Error happens here
Set keyMap = oPara.getMarkupInfoContainer

Set s = oPara.getText
oPara.commitStringMarkup 1, "test", 0, s.Length, keyMap

When GetFirstPara is called, a following exception is thrown:

Windows Script Host
Scenario:	C:\Users\Oleg\Desktop\bugdemo.vbs
String:	7
Symbol:	1
Error:	[automation bridge]UnoConversionUtilities<T>::anyToVariant 
Unexpected exception occurred. Message: SwXFlatParagraph::getPropertySetInfo(): not implemented
Code:	800A03E9
Source: 	[automation bridge] 


Am I doing something wrong (are there any alternatives?) or it is a bug?


No answer so far so I think it’s a bug and added it here: https://bugs.documentfoundation.org/show_bug.cgi?id=89794
Unfortunately doesn’t look like it will be fixed soon…
