Hmm, a quick tip:
try using:
<a jwcid="@tacos:AjaxDirectLink" action="listener:doAddImage"
updateComponents="ognl:{'images'}">Add Image</a>
instead of
<a jwcid="@tacos:AjaxDirectLink" listener="listener:doAddImage"
updateComponents="ognl:{'images'}">Add Image</a>
(note that I changed "listener" for "action").
That might work. Normal listeners are executed "on the spot". So, if
your blogPost is assigned after the AjaxDirectLink, the listener is
executed first, and the post is assigned later. The "action" parameter
defers all listener executions until all of the form elements are processed.
If that doesn't work, please post your code here to check it out.

Hi,
I'm new to Tacos (and Tapestry) and I'm trying to make some forms for
adding/editing inter-related objects. What I'm trying to do is
probably very simple, but I'm missing something to get it all working.
Here's a simplified example: I have a BlogPost and BlogPostImage
classes and I want to create a single form that will allow me to
specify the fields of the BlogPost and add any number of BlogPostImage
objects to that BlogPost.
I was able to take the AjaxForm examples that use "notes" and get
something like that to work for adding/editing my BlogPostImage
objects, but I can't seem to figure the "right" way to associate those
BlogPostImage objects with my BlogPost.
I have:
<property name="blogPost" persist="session"/>
in my .page file.
In my .html template file I have something like this for adding new
(empty) BlogPostImage object:
<a jwcid="@tacos:AjaxDirectLink" listener="listener:doAddImage"
updateComponents="ognl:{'images'}">Add Image</a>
The problem is that in the doAddImage() method, the getBlogPost()
always returns null. So, I guess my question is: How do I make that
blogPost available when I invoke the AjaxDirectLink? I thought that
this would happen automatically since it was set to persist. Do I
have to pass it as a parameter to the doAddImage() listener method?
Hopefully not ...
I hope my question makes some sense. Thanks in advance for any tips.
Hans
