Flash Builder 4 maxDisplayedLines comes back Error #2007 Parameter child must be non-null

I'm fairly new to flash builder and have made a working RSS feed reader, but I can't get the maxDisplayedLines to truncate the text at the end of my RichText object. It comes up with Error #2007 Paramater child must be non-null but I don't have a clue what would be null. The text I'm displaying is coming from textflow 

textFlow="{TextConverter.importToFlow(rdesc, TextConverter.TEXT_FIELD_HTML_FORMAT)}"

and everything displays fine, even the thumbnails until I try to set the max lines. This is for mobile by the way.

the error is TypeError: Error #2007: Parameter child must be non-null. at flash.display::DisplayObjectContainer/addChild() at flashx.textLayout.factory::TextFlowTextLineFactory/callbackWithTextLines()[C:\Vellum\branches\v2\2.0\dev\output\openSource\textLayout\src\flashx\textLayout\factory\TextFlowTextLineFactory.as:267] at flashx.textLayout.factory::TextFlowTextLineFactory/createTextLinesInternal()[C:\Vellum\branches\v2\2.0\dev\output\openSource\textLayout\src\flashx\textLayout\factory\TextFlowTextLineFactory.as:245] at flashx.textLayout.factory::TextFlowTextLineFactory/createTextLines()[C:\Vellum\branches\v2\2.0\dev\output\openSource\textLayout\src\flashx\textLayout\factory\TextFlowTextLineFactory.as:104] at spark.components::RichText/createTextLines()[E:\dev\4.y\frameworks\projects\spark\src\spark\components\RichText.as:1296] at spark.components::RichText/http://www.adobe.com/2006/flex/mx/internal::composeTextLines()[E:\dev\4.y\frameworks\projects\spark\src\spark\components\RichText.as:1173] at spark.components.supportClasses::TextBase/updateDisplayList()[E:\dev\4.y\frameworks\projects\spark\src\spark\components\supportClasses\TextBase.as:685] at spark.components::RichText/updateDisplayList()[E:\dev\4.y\frameworks\projects\spark\src\spark\components\RichText.as:1131] at mx.core::UIComponent/validateDisplayList()[E:\dev\4.y\frameworks\projects\framework\src\mx\core\UIComponent.as:8999] at mx.managers::LayoutManager/validateDisplayList()[E:\dev\4.y\frameworks\projects\framework\src\mx\managers\LayoutManager.as:736] at mx.managers::LayoutManager/doPhasedInstantiation()[E:\dev\4.y\frameworks\projects\framework\src\mx\managers\LayoutManager.as:819] at mx.managers::LayoutManager/doPhasedInstantiationCallback()[E:\dev\4.y\frameworks\projects\framework\src\mx\managers\LayoutManager.as:1180]

 html text show in mobile textarea.

 <s:TextArea id="ric" width="200" height="100"/>

 var textrichtml:String = "<p><b>Scott Carpenter Architect Pty Ltd is a design based</p>";
 TextField(ric.textDisplay).htmlText = textrichtml;
