In GWT, If one widget can contain another widget, It must be implement HasWidgets<http://google-web-toolkit.googlecode.com/svn/javadoc/latest/com/google/gwt/user/client/ui/HasWidgets.html>interface.
So if you wnat int add a widget to your "GWT Text Area", you first should check your "GWT Text Area" whether implement HasWidgets<http://google-web-toolkit.googlecode.com/svn/javadoc/latest/com/google/gwt/user/client/ui/HasWidgets.html>or not.
