Re: nested loop view
User error :)
review what element your adding the inner list to... looks like your
adding it to the ListView instead of the Item.
Change:
this.add(projects);
to
item.add(projects);

Ahh ... but of course!
Thanks both of you. The nested structure did indeed obscure the problem.
Fixed and refactored a bit - and now working as expected.
Thanks for your time!

Re: nested loop view
i think you mean to add the projects listview to the categories list view
/item/
your structure is a little dangerous here because you have one ListItem item
obscuring the other. if the outer one were called outerItem and the inner
one
were called innerItem, i think you meant to say outerItem.add(projects) and
innerItem.add(link)

Re: nested loop view
I think you have to add "projects" to the current category item, not
to "this" (which would refer to the categories listview itself).
So try replacing:
this.add(projects);
By:
item.add(projects);

nested loop view
I'm trying to create a page - similar to Jira's BROWSE PROJECTS.
My initial take amounts to a loop in a loop.
The outer loop is CATEGORIES and the inner loop is PROJECTS in said
category.
| CATEGORY 1
| p1
| p2
| p3
| CATEGORY 2
| p4
| p5
| p6
...
I've attached code below but if I removed the nested loop, I can easily loop
over just CATEGORIES but as soon as I add the nested loop, it fails with the
following
WicketMessage: Error attaching this container for rendering: [Page class =
com.fuzzybearings.milestones.web.page.user.ProjectsPage, id = 3, version =
0]
Root cause:
java.lang.IllegalArgumentException: A child with id 'projects' already
exists:
[MarkupContainer [Component id = categories]]
My intuition tells me that 'wicket:id="projects"' is repeating since it is
contained in an outer loop ... but I'm not sure how else to identify this
type of structure in a general way. Is there a loop container more suited to
this ... open to suggestions.
Thanks in advance,
