The placeLoadStringInApplicationSandbox property only applies to the HTMLLoader class (or the Flex HTML component, which wraps HTMLLoader).
If you are trying to use any other Flex component that uses a standard ActionScript TextField under the covers for text display, there is no corresponding way to designate that the htmlText content should be treated as application sandbox content.
Am I right in assuming that every Flex/AIR TextField is based on a standard Actionscript TextField?
So do you have any idea how to implement something like that?
Do you think creating a TextField in AS3 instead of using the <mx:TextField /> would be helpful?
I'm not really sure about that, because in the AS class of the Flex Textfield there is nothing, which says "no img-tag". It extends the standard TextField of AS. I was hoping to override simply one of the methods but there is nothing to override in the Flex AS class of a TextField. So there must be something in the standard TextField class which causes the problems, right?
Thanks a lot for helping,
Did anyone ever get any closer to a solution for this?
