> TLF Lists which have ParagraphElements with hanging indents do not render
> correctly
> -----------------------------------------------------------------------------------

> Key: FLEX-33693
> URL: https://issues.apache.org/jira/browse/FLEX-33693
> Project: Apache Flex
> Issue Type: Bug
> Affects Versions: Apache Flex 4.10.0
> Reporter: Harbs
>
> A hanging indent is defined by setting the paragraphStartIndent to a positive
> number and the textIndent to an inverse negative number. This work correctly
> as long as you specify a tab stop at the position of the
> paragraphStartIndent. (I don't know if this desired behavior or not.)
> If the paragraph is in a ListItemElement, the text is not tabbed to the
> position of the paragraphStartIndent. It seems the textIndent value is
> subtracted for the calculated tab location of the entire line. The text is
> instead tabbed to the next tab position.
> Possible workaround:
> Specifying a tab position at double the paragraphStartIndent causes the text
> to look correct, but only because the text is shifted to the left the amount
> of the textIndent.
> Below, I will attach a sample application which illustrates these points.
