HtmlText is an odd beast. I think Robert may be on the right track when he wonders about it being an add-on. Try this:

Paste the following html list markup in field "source":

<ol>
<li>List item 1</li>
<li>List item 2</li>
</ol>

Now use it as the source to set the htmlText of another field "dest":

  set the htmlText of fld "dest" to fld "source"

Now examine the htmlText of fld "dest". You get this:

<ol type="1">
<li>
<p>List item 1</p>
</li>
<li>
<p>List item 2</p>
</li>
</ol>

Now manually select the text in fld "dest" and hit delete. The contents of fld "dest" looks like this:

1.

No matter what you do you can't manually delete the first list item marker. The htmlText of "dest" now looks like this:

<ol type="1">
<li>
<p></p>
</li>
</ol>

The field thinks it's a list and you can't change it's mind. Unless you do this:

  put empty into fld "dest"

At which point the htmlText is <p></p>. Which is where this all started. :)

We had an interesting discussion of the html list issue in the Quality Control center a couple of years ago: http://quality.runrev.com/show_bug.cgi?id=9342
