on second thoughts, I'm not sure I follow the design here.
Greg, how is TextAreaContentListener meant to be used?
I would have thought that it would expose events for changes to the content of a paragraph as well as changes in the Sequence<Paragraph> collection.
Or am I missing something?

That's a valid bug. Please log a JIRA issue for that.

Hi,

I'm trying to get information about text removed from TextArea component. In the ParagraphListener, which I used for text changes tracking, there are two methods:

- void textInserted(Paragraph paragraph, int index, int count) - this one is perfect for me, I can retrieve inserted text from the paragraph's CharSequence (using getCharacters() method), I have all I need: index and count - void textRemoved(Paragraph paragraph, int index, int count) - here my problem begins, paragraph received as parameter has no text I'm looking for because is has been already removed.

Of course I can make a deep copy of paragraph's characters (every time it changed) and search for my removed text using previously created copy, but is it really the only way I can do that? It's quite expensive.

I checked the source and in the TextArea.Paragraph class in the method void removeText(int index, int count) there is a line where real text removal operation takes place: characters.delete(index, index + count), but removed text is not stored or passed to any of the listeners.

Thanks,
Rafal
