As the title says, using loadstyle() on a textfield does not work on Flash, it does on HTML5.
Using set() or copy() does works on both though, but is not practical if I want to set a new style with lots of attributes.
I uploaded a little example here: uruguay360.com.uy/loadstyle_bug (xml) It seems that the values of the new style are copied, but are not used by the plugin.
Best regards,
Hernán
