HTML :: How To Get DIV Tag To Wrap Inside AdvancedDataGridColumn

To display HTML formatted text in an AdvancedDataColumn, I'm using a custom renderer which is an mx:Text object. I'm setting myText.htmlText to something like "test text which is really a lot longer than the column width". No matter what properties I set though, the text just runs off the end of the column. I tried wordWrap="true" on the dataGrid and also on each individual column. I also tried messing with css and tried applying it to the text field, but nothing seems to show up. Any Way to wrap htmlText in a text object? Also, but slightly less important, there are extra blank lines after each tag which I would like to get rid of.

Renderer code.
