that's how I thought it worked too (after some puzzling) .. some
documentation would be nice and make things clearer!

Hi Marco
As far as I understand it, the widget generates a string with the
expected value and gives this an id.
This is stored in the session. When rendering the widget to html an
image with the name capcha-{id}.jpg is requested. Cocoon now takes
this id to generate the image for that particular id containing the
information in the session. All the Validator has to do now is to
compare the value entered with the one stored in the session.
Hope I’m correct.

*Betreff:* How does the captcha valid. in forms work?
Hello,
I know how to put in in the form and make it work, but what I do not
understand is how it works, especially whats in the sitemap
you put s.th <http://s.th> like that in your form:
<fd:captcha id="captcha" required="true" length="5">
<fd:datatype base="string"/>
<fd:validation>
<fd:captcha/>
</fd:validation>
</fd:captcha>
sitemap:
<map:match pattern="captcha-*.jpg">
<map:generate type="jx" src="documents/xml/captcha-image.xml">
<map:parameter name="capt" value="{session-attr:captcha-{1}}"/>
</map:generate>
<map:serialize type="svg2jpeg"/>
</map:match>
does it mean this: <fd:captcha id="captcha" required="true"
length="5"> calls that: <map:match pattern="captcha-*.jpg">
and what about this entry: value="{session-attr:captcha-{1}}" ??
A description of the whole process would be great....
Thank you
Marco
