I don't see any problems with users editing the text for the two use
cases I've outlined:
1) You want to display HTML formatted text, but you also want to have
inputtext look&feel
In this use case, the text is only displayed, thus not editable.
2) To insert pre-formatted text with line breaks in an inputtext. Just
one day ago I've responded to this thread [1] in the German OpenLaszlo
forum and that thread was about exactly this issue!
Any <br> line-breaks are automatically changed to \n (resp. \r in Flash).

So, what happens, when you have set an inputtext element to display HTML and
the user edits the text? How does the editing interact with the (essentially
invisible) markup?

As stated earlier [1], sometimes it is useful to have HTML capability for
inputtext.

oh yes, you're right, I guess we never did that.
If someone wants to style an input field, they can set the font
size/style on an input text field without calling setHTML. But if there
are style changes in the text
it's just going to make a mess when they start editing it.
I notice that we have a capabilities for this feature, which is disabled for
DHTML, maybe we should should disable it for swf also, so people get
a warning in the debugger, and don't expect it to do anything useful.

"setHTML(..)" is only defined on lz.inputtext. There is no
corresponding method for lz.text, is it? See LPP-6617

Hi Roger,
The inputtext class doesn't support HTML formatting in any useful way right
now. It inherits the
setHTML flag from lz.text, but the behavior is not well defined when you
start entering text.
There is a rich text editor component that is specific to Flash 8, in the
incubator/rich-text directory,
but it works by doing low level calls to the Flash TextField and TextFormat
objects directly.
That component could probably be made to work in swf910 with some effort,
but it's a somewhat difficult
task, because the code pokes directly into the LzSprite object, and that
implementation has diverged
somewhat from swf8 to swf10.
We're looking at the design of an updated text class that can take advantage
of some of the
powerful features of Flash 10's text engine. The challenge will be to see
how to expose these
new features and also try to have as much cross-platform compatibility as
possible with the
DHTML runtime.
