various templates have this warning:

<textarea name="description" class="lenya-form-element"><jx:out
value="${request.getParameter('description')}"/></textarea>
unfortunately, all browsers i have tried cannot handle
<textarea/>
to prevent the serializer from collapsing <textarea> (and <script>),
there are 2 options:
* switch to the serializer from the serializers block
* add a space if the textarea value is empty
option 1 works, but that serializer has other problems that make the
site area no longer work
Would it be possible to use one serializer for the site area, and the
other for the remaining areas ?
so i added this stylesheet to strip_namespaces:
<xsl:template match="textarea|script|style">
<xsl:element name="{local-name()}">
<xsl:copy-of select="@*"/>
<xsl:apply-templates/>
<xsl:if test="string-length(.) = 0"><xsl:text> </xsl:text></xsl:if>
</xsl:element>
</xsl:template>
i do not see a way around this, and google didn't have better ideas
either. comments?
The problem is two-fold;
- usability: when the user gets a form with an empty text area, that
area will always contain a space, so if she selects that field and
starts typing, her text will have a space before it (that's why I
removed the spaces in the XSL, I wasn't aware of this browser bug, I'm
guessing it's an ... IE bug ?)
- storage: the field gets stored even if the user put no meaningful
value in it. We could of course check for that in the code.
Maybe another option would be (but you're probably not going to like
this) to have browser-specific code. If we have workarounds in the
stylesheets because of browser bugs anyway, we might as well make them
explicit and have them applied only for the browser family requiring them.
