Weird issue round tripping with TLF

For the issue with spaces being removed from XML, its probably with the fact that XML's ignoreWhiteSpace property defaults to true.  Change it to false to preserve spaces.

What I ended up doing, is on the point of save I make a copy of my textflow,

then loop through all spans and replace spaces with a carot ^, then on render, i loop through all spans and replace the ^ with the space.

This works perfect, although it is a hack.

ON SAVE :

                var copy:TextFlow = TextConverter.importToFlow(TextConverter.export(txt.textFlow,TextConverter.TEXT_LAYOUT_FORMAT, ConversionType.STRING_TYPE), TextConverter.TEXT_LAYOUT_FORMAT);
                for(var i:Number = 0; i < copy.numChildren; i++){
                    var p:ParagraphElement = copy.getChildAt(i) as ParagraphElement;
                    for(var j:Number = 0; j < p.numChildren; j++){
                        var s:SpanElement = p.getChildAt(j) as SpanElement;
                        s.text = s.text.split(" ").join("^");
                    }
                }
                var res:String = TextConverter.export(copy, TextConverter.TEXT_LAYOUT_FORMAT, ConversionType.STRING_TYPE).toString();

ON RENDER :

                for(var i:Number = 0; i < txt.textFlow.numChildren; i++){
                    var p:ParagraphElement = txt.textFlow.getChildAt(i) as ParagraphElement;
                    for(var j:Number = 0; j < p.numChildren; j++){
                        var s:SpanElement = p.getChildAt(j) as SpanElement;
                        s.text = s.text.split("^").join(" ");
                    }
                }
