> Within the textChanged listener on my TextArea, I (naturally) call getText.
> This works fine if textChanged was called as a result of typing into the
> TextArea. But if it was fired because of a call to setText elsewhere in my
> program, getText throws IndexOutOfBoundsException. The stack looks like this:
> ArrayList<T>.verifyIndexBounds(int, int, int) line: 577
> ArrayList<T>.get(int) line: 346
> TextArea.getParagraphAt(int) line: 853
> TextArea.getText(int, int) line: 632
> TextArea.getText() line: 606
> <mycode>$2.textChanged(TextArea) line: 122
> TextArea$TextAreaContentListenerList.textChanged(TextArea) line: 518
> TextArea$ParagraphSequence.remove(int, int) line: 421
> TextArea.setText(Reader) line: 722
> TextArea.setText(String) line: 667
> My workaround is to check for getCharacterCount() being positive before
> calling getText.
> Here's a test case:
> <Window title="Empty text area bug" maximized="true"
> xmlns:bxml="http://pivot.apache.org/bxml";
> xmlns="org.apache.pivot.wtk">
> <BoxPane orientation="vertical" styles="{fill:true}">
> <PushButton buttonData="Set text">
> <buttonPressListeners>
> function buttonPressed(button) {
> textArea.setText("This is some text");
> }
> </buttonPressListeners>
> </PushButton>
> <TextArea bxml:id="textArea">
> <textAreaContentListeners>
> function textChanged(textArea) {
> importPackage(org.apache.pivot.wtk);
> Alert.alert(MessageType.INFO, "Text is " + textArea.getText(),
> textArea.getWindow());
> }
> </textAreaContentListeners>
> </TextArea>
> </BoxPane>
> </Window>
