Key: FLEX-34020
URL: https://issues.apache.org/jira/browse/FLEX-34020
Project: Apache Flex
Issue Type: Bug
Components: Spark: RichText
Affects Versions: Apache Flex 4.11.0, Apache Flex 4.9.0
Environment: Windows 7 and OS X.
Reporter: Curtis Aube
Priority: Critical
Sometimes the RichText component gets a null object reference when truncating
text.
Here is an example:
{code:ActionScript}
<?xml version="1.0" encoding="utf-8"?>
<s:Application creationComplete="creationComplete()" minHeight="600"
minWidth="955" xmlns:fx="http://ns.adobe.com/mxml/2009";
xmlns:mx="library://ns.adobe.com/flex/mx"
xmlns:s="library://ns.adobe.com/flex/spark">
<fx:Script>
<![CDATA[
import flashx.textLayout.conversion.TextConverter;
import flashx.textLayout.elements.TextFlow;
private function creationComplete():void
{
var htmlText:String = "<ul><li>This is a test
of a sentence that is really long. So long that it causes a null object
reference for some reason.</li></ul>";
htmlText += "Lorem ipsum dolor sit amet,
consectetur adipiscing elit. Sed volutpat neque tellus, vitae pellentesque
lectus posuere eget. Donec eget congue nisi, vel consectetur massa. Morbi
suscipit justo neque, at varius arcu imperdiet sit amet. Phasellus volutpat
nulla mauris, ac suscipit arcu condimentum vitae. Sed lobortis ligula enim, eu
egestas diam congue quis. Nullam pellentesque condimentum mi, eu tincidunt eros
imperdiet elementum. In blandit risus ac lorem tincidunt, quis sagittis felis
euismod. Vestibulum justo nibh, imperdiet pharetra iaculis vel, fermentum in
dolor. Fusce ut urna pharetra, commodo felis in, rhoncus metus. Pellentesque
facilisis, tortor at feugiat dignissim, dui lectus tempor justo, ut condimentum
massa mi quis risus. Pellentesque sodales, massa ut sodales fringilla, augue
dolor cursus eros, ac pretium est nisl a eros. Etiam nec erat dapibus,
scelerisque nibh et, consectetur risus. Nullam vitae convallis leo. Aliquam sed
lorem facilisis, fringilla quam ut, semper urna. ";
var tf:TextFlow =
TextConverter.importToFlow(htmlText, TextConverter.TEXT_FIELD_HTML_FORMAT);
rt.textFlow = tf;
}
]]>
</fx:Script>
<s:RichText id="rt" width="600" maxDisplayedLines="10"/>
</s:Application>
