Split and Merge Paragraphs

Question

When I split and merge a paragraph a line break is inserted.  Does anyone know a way around this. (Simply deleting the last character seems inelegant and, more importantly, prone to failure).  Here's the code:
var textFlow:TextFlow = TextConverter.importToFlow(
                    "Hello World",
                    TextConverter.PLAIN_TEXT_FORMAT);
textFlow.interactionManager = new EditManager();
var textFlow2:TextFlow = textFlow.splitAtPosition(5) as TextFlow;
textFlow2.interactionManager = new EditManager();
textFlow.mxmlChildren = textFlow.mxmlChildren.concat(textFlow2.mxmlChildren);
trace(textFlow.getText()); // returns "Hello\n World"

If you are asking how to split and merge a paragraph this works.
            var textFlow:TextFlow = TextConverter.importToFlow("Hello World",TextConverter.PLAIN_TEXT_FORMAT);
            // find the paragraph
            var para:ParagraphElement = textFlow.findLeaf(5).getParagraph();    // same as textFlow.getChildAt(0)
            // split paragraph at position five
            var newPara:ParagraphElement = para.splitAtPosition(5) as ParagraphElement;
            trace(textFlow.getText());
            // now the merge
            // remove newPara its being discarded
            newPara.parent.removeChild(newPara);
            // move the children
            while(newPara.numChildren)
                para.addChild(newPara.getChildAt(0));
            trace(textFlow.getText());
This is using pure model level calls.  In your original code you added an EditManager- it can be done that way too.  TLF is layered - the EditManager manipulates the model with model level calls.  It provides APIs connected to events that create operations do to that.
Hope that helps,
