Thanks, that worked a treat. Now that I know how to make the AJAX system do 
updates like that I might well play around with other things I can do :D. I 
shall look at that helper class soon though to make sure I'm not making 
needless updates on that output.

Thanks again your help it's been marvellous.

Hi people,

I'm using CForms in Cocoon 2.1.8 and I've run into a bit of a problem
(I sort of posted about this a while back so a bit of this is a
repost). I was trying to feed some HTML into the form to provide
output to the user. To do this I use a pipe that generates XML output
and then I try and serialize that into the document using the JX
template stuff that looks like:

 

Unfortunately that doesn't dynamically regenerate when the op-list

that would be the best solution by far).


You should be able to get the AJAX framework to update that snippet of 
code by wrapping it in a bu:replace element when it needs to be updated. 
 Anything that is wrapped in a bu:replace will be sent to the browser 
in the AJAX response and updated in the page.



  

value="${Packages.org.apache.cocoon.xml.StringXMLizable(xhtmlString)}"/>

  


  
http://apache.org/cocoon/browser-update/1.0";>
  ${xhtml}

  
  ${xhtml}


That's untested but should be along the lines of what you need.  Notice 
the  with the identical id attribute as the only child of 
bu:replace - this is the element that will be inserted into the page, 
and its id marks it as the target for future updates.


You'll also probably want to add logic to only add the bu:replace when 
the widget's value has been udpated.  Since you're already importing the 
CForms jx-macros file you'll have access to the 'cformsHelper' variable 
which is a helper class that has some tools for this sort of thing.


Hope that helps

If I go for a straight up output then I just get the
Moo tags displayed. I looked at serialization on
the forms-field-styling.xsl, as XSLT 1.0, and therefore Xalan (AFAIK)
doesn't have a serialize function I looked at creating one that
looked something like this:


  
 function serialize(xmlString) { var
output = Packages.org.apache.cocoon.xml.StringXMLizable(xmlString); 
if(output == null) { output = "Oh Dear"; } return output; } 
 


but that just generated NULL values so I gave up on that.

I even wrote a stylesheet to convert the HTML into Text and just use
output but IE seems to ignore the line breaks on the  tag when
you insert it in dynamically (damn IE).

Any ideas on how to get the AJAX stuff to display this dynamically
when the value changes?

Thanks,

Gary
