Error pasting data into a TextInput

In my Flex 4 application I have a spark text input. When the user pastes data from clipBoard it throws error if the clipBoard contains a different format (other than string). This is the error message i am getting.

"TypeError: Error #1009: Cannot access a property or method of a null object reference.
    at spark.components::RichEditableText/handlePasteOperation()
开发者_如何学Go[E:\dev\4.0.0\frameworks\projects\spark\src\spark\components\RichEditableText.as:3611]"

Is there any way to handle this?

Thanks Manoj

It looks like this is a known problem. The only suggestion I could find was from rdermer on one of those threads:

If you have a local copy of TLF 1.1 you can work around it by adding a test at line 346 of TextClipboard.as. Replace endArray.push(curFlElement); with if (curFlElement) endArray.push(curFlElement); That prevents the bug - but the underlying cause needs more investigation.
