Issue with AjaxLinks in ListView
Hi,
I have a page that has a panel with ListView<AjaxLink> (Listview
contains AjaxLink's).
I go to that page, click on a links - does an ajax update of one section
in a page, and then I do a target.addComponent(listViewPanel) to update
the link selection background. This works fine so far.
Now I click on the second link in that listview, I am getting the below
exception:
org.apache.wicket.WicketRuntimeException: component
heading:menu:subMenuBar:topmenuitems:2:menuitemfragment:linkfragment:lin
kid not found on page
com.infoblox.nios.ui.page.datamgt.DataManagePage[id = 3], listener

at
org.apache.wicket.protocol.http.WicketFilter.doGet(WicketFilter.java:355
)
NOTE: THIS PROBLEM IS VERY INTERMITTENT, I am unable to determine the
main cause for this. However, if I re-login, everything is fine (atleast
was able to click on the links multiple times, and did not see any
issues).
I am using Wicket 1.3.5
Please let me know if you have any ideas, any pointers would be highly
appreciated.
Best Regards & Thanks in Advance,
Kuga

It's hard to say what's going wrong without seeing code for entire page.

Replaced it with Repeating views, and seems to work so far, will know better
results in couple of days if there are any issues. Thanks JK for the support
& help with some ideas. Much appreciated.
Really wonder why that should give such wierd behavior for ListView
Thanks

Hi,
I tried using the setReusableItems(true) in the constructor,
still no luck.
I have not tried replacing to RepeatingView. Will it make a difference?
Thanks

Hi Kuga,
ListView re-creates all its child items on each render, which might be
causing your problems. Try calling setReuseItems(true), or better still,
consider using RepeatingView instead.

Hi,
Thank you for your response,
here is the ListView code:

private int selectedIndex = 0;
private SubMenuListView(final String id, final IModel model) {
super(id, model);
}
private SubMenuListView(final String id, final List<MenuItem> list)
{
super(id, list);
}
/* (non-Javadoc)
* @see org.apache.wicket.markup.html.list.ListView#newItem(int)
*/
@Override
protected ListItem newItem(int index) {
// TODO Auto-generated method stub
return new ListItem(index, getListItemModel(getModel(), index)){
/* (non-Javadoc)
* @see
org.apache.wicket.Component#onComponentTag(org.apache.wicket.markup.ComponentTag)
*/
@Override
protected void onComponentTag(ComponentTag tag) {
String cssClass = (String)tag.getString("class"); //$NON-NLS-1$
if (cssClass == null)
{
cssClass = " "; //$NON-NLS-1$
}
if (((MenuItem)getModelObject()).isSelected())
{
cssClass = "menu2-selected-long"; //$NON-NLS-1$
} else{
cssClass = " "; //$NON-NLS-1$
}
tag.put("class", cssClass.trim()); //$NON-NLS-1$
super.onComponentTag(tag);
}
};
}
@Override
protected void populateItem(final ListItem item) {
final MenuItem menuItem = (MenuItem) item.getModelObject();
if (menuItem.isSelected()) {
if(menuLevel.equals(MenuLevel.TOP)) {
item.add(menuIsSelected); //set CSS class if the
top-level menu item is selected
}
else if(menuLevel.equals(MenuLevel.SECOND)) {
item.add(menuIsSelectedLong); //set CSS class if the
second-level menu item is selected
}
}
item.add(new MenuItemFragment(menuItem));
}
