My little problem with Tap listing

[JeffersON <n3...@rtrtr.com>]

OK, I have quite complicated situation here. I have made one component for
listing all my blogs, and in that component I have made one specific method
for redirecting user to a BlogFullPage

@InjectPage
private BlogFullPage fullBlogPage;

//code trimmed 

@CommitAfter
public String onActionFromBlogFullPage(Blog blog){
fullBlogPage.setBlogSpecific(blog);
return fullBlogPage;
}

Now for that page I have made the following

public class BlogFullPage {
@Property
@Persist
private Blog blog;

public Blog getBlogSpecific(){
return blog;
}

public Blog setBlogSpecific(Blog blog){
this.blog=blog;
}

Now my tml for BlogFullPage looks like this
<t:layout .....>
<div class="div1_set2">
${blog.name}....//code trimmed

and with all of that I have added one component for listing comments for the
specific blog with
<t:listComments></t:listComments>


My listComments page and tml look like this

<PostDisplay
xmlns:t="htttp://tapestry.apache.org/schema/tapestry_5_0_0.xsd">
<t:loop source="comments" value="comment">
<div class="div3_sec1">
${comment.name}
${comment.from}
</t:loop>
</PostDisplay>

and my java looks like

public class ListComments{
@Inject
private Session session;

@Persist
@Property
private Blog blog;

@Persist
@Property
private Comment comment;


public List getComments()
{
   List l;
   l =
session.createCriteria(Comment.class).add(Restrictions.eq("id",blog)).list();
   return l;
}

However, everything works fine, except it doesn't list my comments for
specific blog!? I was thinking maybe Tap doesn't know in the runtime which
id of what blog is passed to it, and therefore doesn't return anything,
however when I put only this

public List getComments()
{
   List l;
   l = session.createCriteria(Comment.class).list();
   return l;
}

it lists just fine comments, however all comments are the same for every
blog, which is not what I want. What did I do here wrong, maybe some little
help would be appreciated.

Thanks in advance.

I gues you want to use the foreign key pointing from comment to blog, but you are using the "id" (autoinc pk of comment?) instead.

session.createCriteria(Comment.class).add(Restrictions.eq("id",blog)).list();
  return l;

Should Restrictions.eq("id",blog) be Restrictions.eq("blog",blog)

Also I would use blog as activation context in the second page. @Persist should be avoided if possible.
