tacos partial form

[haipeng du <ha...@gmail.com>]

I use tacos partial form to handler ajax. The html likes following:
<form jwcid="@tacos:PartialForm" listener="ognl:listeners.submit"
id="docTypeForm">
  ....
  ....
   <input type="submit" jwcid="@Submit" label="Search"  
                                    tag="Search" selected="ognl:command"/> 
</form>
When I click button, form is submitted. But in listener method
submit(IRequestCycle cycle), I can not get command. It is null when I
output getCommand(). If I change form to tapestry Form, I can get the
command filled.
Could somebody have some idea to solve that?
Thanks a lot.

Currently Submit does not correctly cooperate with PartialForm. You can use 
LinkSubmit instead.
I will provide a patch for it if noone does it but now I'm nearing deadline 
with one of my projects...

If you'd do it: the problem is that partial submit is not a real form 
submit, the PartialForm component manually collects the values of the input 
fields using javascript.
So the name of the clicked submit button won't be included in the request 
parameters (in case of a normal submit the browser would include it after 
the click).

The patch is very simple: LinkSubmit should be used with a button renderer. 
The only problem is that LinkSubmit does not have a "renderer" parameter 
(unlike DirectLink, etc.), so this should be implemented. I would prefer 
adding a renderer parameter to Tapestry's LinkSubmit but if it is not 
accepted by Tapestry developers then the source code of LinkSubmit should be 
copied to Tacos with some modifications as PartialSubmit.

Hope this helps,
Norbi
