Adding a Link for a Whole ListItem
With a ListView is there a way to actually create a Link component
that encompasses the whole ListItem, such that when you click anywhere
on a row the onClick event is fired? I know you can do this with Ajax
support, but I'm curious if you can do this using the traditional way,
i.e., with a full page refresh. I don't want to add a "click here"
button to my row.

Re: Adding a Link for a Whole ListItem
Posted by Christopher Gardner <ch...@gmail.com>.
I'm continuing to experiment with making a click of a row do a page
refresh. I coded up a class called LinkableListView that uses a
LinkableListItem, which implements ILinkListener. When the
LinkableListItem's onLinkedClick() is called, LinkableListItem
delegates back to LinkableListView.onClick().
Here is the what my LinkableListView generates for the 2 <tr>'s.
<!-- for row zero -->
...
<tr onclick="window.location.href='?wicket:interface=:0:plan:0:::ILinkListener::';return
false;">
...
<!-- for row one -->
<tr onclick="window.location.href='?wicket:interface=:0:plan:1:::ILinkListener::';return
false;">
To use this component, I created a very simple page with two tables.
One table contains a list of objects fetched from memory. These
objects are fetched only once (at WebPage construction time). Now
when I click on a row, I want the data from the LinkableListItem in
the selected row to be popped over to the second table which is
designed to hold only a single row.
In this simple page, EVERY time I click on a row in table 1, I get the
page expired message. I'm new to Wicket, so please forgive and blot
out my ignorance.

Look up how requesttargets work in wicket. In particular
look up ListenerInterfaceRequestTarget for this use case.
It just knows how to call ur component(link for example)
in ur page object. Call will land in onLinkClicked.

Re: Adding a Link for a Whole ListItem

Thank you. I got this to work. Now I'm wondering how the
ILinkListener gets registered to pick up the event. Does anything
that happens to implement that interface automatically get registered?

Yes, but odds are you already had to do that, to override populateItem().

Do you also have to subclass ListView (overriding newItem()) to create
an object of the ListItem subclass?

Re: Adding a Link for a Whole ListItem

Yes you can, The trick is to extend ListItem and have it implement
ILinkListener you can then add the onclick behavior through an
attributemodifier or override oncomponenttag. To prevent having to
make a subclass per page you should make the onLinkClicked method in
your listitem redirect to a method in your listview.
I could show you our code but it is cluttered with non relevant code,
and the above really says it all.
