TLF Problems

Question

Hi all,
New here in this forum...
I'm not sure if this is the right place for my question.
I've recently updated my Flash CS5 (Flash Professional CS5 Update 11.0.2 09/07/2010). It seems like it has a bug in the TLF.
I have a little chat app. When ever the user adds another message i create a new ParagraphElement and add it to a TextFlow object(the same one, a private member). It always shows only one line of text, even when there should be 2 or more lines.
Here is the code:
package chat.messageProcessor{
     import flash.display.DisplayObject;
     import flash.display.Sprite;
     import flash.events.EventDispatcher;
     import flashx.textLayout.container.ContainerController;
     import flashx.textLayout.conversion.ConversionType;
     import flashx.textLayout.conversion.TextConverter;
     import flashx.textLayout.edit.SelectionManager;
     import flashx.textLayout.elements.InlineGraphicElement;
     import flashx.textLayout.elements.ParagraphElement;
     import flashx.textLayout.elements.SpanElement;
     import flashx.textLayout.elements.TextFlow;
     import flashx.textLayout.events.CompositionCompleteEvent;
     import flashx.textLayout.events.FlowOperationEvent;
     import flashx.textLayout.events.SelectionEvent;
     import flashx.textLayout.operations.CopyOperation;

Thanks fopgames.
Is this what you mean: _textFlow.multiline = true;
I must add the there is no TLFTextField instance in use.
