Justin Mclean commented on FLEX-34013:
--------------------------------------

Thanks for the code to reproduce the issue.

The issues is related to this code:

                    // If copied/cut from displayAsPassword field the pastedText
                    // is '*' characters but this is correct.
                    var pastedText:String = staticPlainTextExporter.export(
                        po.textScrap.textFlow, ConversionType.STRING_TYPE) as String;
                    
                    // If there are no newlines there is nothing
                    // more to do.
                    if (pastedText.search(ALL_NEWLINES_REGEXP) != -1)
                    {
                        pastedText = pastedText.replace(ALL_NEWLINES_REGEXP, "");
                        po.textScrap = 
                            TextClipboard.importToScrap(pastedText, po.textScrap.isPlainText()
?
                                TextConverter.PLAIN_TEXT_FORMAT : TextConverter.TEXT_LAYOUT_FORMAT);
                    }

i.e. calling importToScap a second time when pasting text that contains a new line

In the second import it calls importToFlow which calls importFromString and then importFromXML:

		protected function importFromXML(xmlSource:XML):TextFlow
			// Parse an XFL hierarchy into a TextFlow, using the geometry supplied by a TextFrame
			// to host child containers (e.g. tables). This is the main entry point into this class.
		{
			return parseContent(xmlSource[0]);
		}

In the second case xmlSource does't have any children and xmlSource[0] does't exist so importFromXML
returns null causing the RTE.

I'm not 100% what the best solution to solve this issue is however.
