将 Flex RTE HtmlText 导入到 TLF TextFlow
我是 Flex/Air 应用程序的开发人员，我们使用有缺陷的 Flex RTE (RichTextEditor) 来让用户管理他的笔记。目前我正在尝试评估使用 TLF（文本布局框架）构建新文本组件的成本有多大。
真正重要的问题是我们是否可以立即导入由 RTE 生成的 HTML 文本。我知道 TLF 1.1 的列表存在一些限制，但它通常有效吗？
我刚刚尝试从 RTE 获取一些 HTML 格式的文本，如下所示：
var htmlText:String = '<TEXTFORMAT LEADING="2"><P ALIGN="LEFT"><FONT FACE="defaultFont" SIZE="14" COLOR="#000000" LETTERSPACING="0" KERNING="0">1hr run on Wednesday - feeling ok!</FONT></P></TEXTFORMAT>'
当我将其传递给 TextConverter 时，如下所示：
var textFlow:TextFlow = TextConverter.importToFlow(htmlText, TextConverter.HTML_FORMAT);
Flash Player 抛出异常。我也尝试用 包裹文本
<html><body></body></html>
，但同样的问题。所以它似乎并不能立即起作用。你有什么经历？这对我们来说确实至关重要。
更新 1：
当我尝试像上面一样导入 HTML（相同的变量声明）时，我收到此错误：
TypeError: Error #1009: Cannot access a property or method of a null object reference.

同时我删除了标签并且它可以工作，但问题仍然存在。
提前致谢！
I am working as a developer on a Flex/Air application and we are using the buggy Flex RTE (RichTextEditor) to let the user manage his notes. At the moment I am trying to evaluate how costly it would be for us to build a new text component using the TLF (Text Layout Framework).
Really important is the question if we can import the HTML text, produced by the RTE straight away. I know that there are some limitations regarding lists with TLF 1.1, but does it work in general?
I have just tried to grab some HTML formatted text from RTE like:
var htmlText:String = '<TEXTFORMAT LEADING="2"><P ALIGN="LEFT"><FONT FACE="defaultFont" SIZE="14" COLOR="#000000" LETTERSPACING="0" KERNING="0">1hr run on Wednesday - feeling ok!</FONT></P></TEXTFORMAT>'
when I pass this to the TextConverter like this:
var textFlow:TextFlow = TextConverter.importToFlow(htmlText, TextConverter.HTML_FORMAT);
The Flash Player throws an exception. I also tried to wrap the text with
<html><body></body></html>
, but same issue. So it does not seem to work straight away. What are you experiences? This is really critical to us.
UPDATE 1:
When I try to import the HTML like above (same variable declaration) I get this error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.

Meanwhile I removed the tags and it works, but the question still remains.
Thanks in advance!

格式有三个常量，其中没有一个似乎不是您使用的：
此外，格式以下“html”代码看起来更像是 TLF 格式的 XML，而不是 HTML。
Take a look at http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flashx/textLayout/conversion/TextConverter.html
There are three constants for the format, none of which seems to be what you used:
Also, the format of the following "html" code looks more like TLF-formatted XML than HTML.
