I don't think that's the problem. The text I'm trying to display comes from XML retrieved via HTTP. If I run the same code without retrieving it from HTTP, the text in both fields displays without the & even though the XML does contain & (otherwise it wouldn't be legal XML). If the edit field always displayed the & I would think that it had something to do with the field displaying plaintext, but it varies depending on whether the XML was local or retrieved via HTTP.
