----------------------------------
Fix Version/s: Apache Flex 4.14.0
> Can't use optionnal importer for TLF plainTextFormat and TextLayoutFormat

> When you add importer to the TextConverter class, you should be able to let
> the importer decline the conversion by having its importToFlow method
> returning null (as it is stated in the TLF blogpost
> http://blogs.adobe.com/tlf/2010/11/custom-clipboard-formats.htm ).
> It works for all format except plainTextFormat and textLayoutFormat because
> of these lines in flashx.textLayout.edit.TextClipboard, method importToScrap
> #170:
> {quote}
> var textFlow:TextFlow = importer.importToFlow(textOnClipboard);
> *if (textFlow)*
> textScrap = new TextScrap(textFlow);
>
>
> if (format == TextConverter.PLAIN_TEXT_FORMAT)
> *textScrap.setPlainText(true);*
> else if (format ==
> TextConverter.TEXT_LAYOUT_FORMAT)
> *textScrap.setPlainText(false);*
> {quote}
> If the importer return null, textFlow==null, so textScrap==null and
> textScrap.setPlainText(...) cause a null object error.
> The solution is trivial. This method should not assume these formats will
> always have the importer return a non-null textFlow, and should test either
> the existence of the textFlow or the existence of the textScrap. The correct
> code would be:
> {quote}
> var textFlow:TextFlow = importer.importToFlow(textOnClipboard);
> if (textFlow)
> textScrap = new TextScrap(textFlow);
>
>
> if (format == TextConverter.PLAIN_TEXT_FORMAT
> *&& textScrap*)
> textScrap.setPlainText(true);
> else if (format ==
> TextConverter.TEXT_LAYOUT_FORMAT *&& textScrap*)
> textScrap.setPlainText(false);
> {quote}
> This bug prevent me from having some converter that check for patterns in a
> plain text from clipboard and chose to handle the conversion if the patterns
> are found.
