Re: adding items dynamically to ListView
Just resolved the issue. The problem was that I wasnt setting
container.setOutputMarkupId(true); before I initially added the container
to the page. I was setting it when the user clicked a button, which always
occurred after the container was initially added.
My original flow was something like this:
WicketPanel class {
...
instantiate container
ajax onClick() {
container.setOutputMarkupId(true);
target.addComponent(container)
}
add(container)
}
It needs to be like this:
WicketPanel class {
...
instantiate container
container.setOutputMarkupId(true);
ajax onClick() {
target.addComponent(container)
}
add(container)
}
Makes sense. Thanks for all the help

adding items dynamically to ListView
I'm trying to add items to a listView when a user clicks a button. I have a
propertyModel backing my ListView. In the onClick(), I do:
AjaxLink newIncButton = new AjaxLink(newIncButton){
@Override
public void onClick(AjaxRequestTarget target) {
List list = new ArrayList(bean.getIncList());
Incident inc = new Incident();
inc.setAction(action);
inc.setDescription(whatever description);
list.add(0, inc);
bean.setIncList(list);
}
}
the variable bean is the object which backs the propertyModel.
The ListView doesn't appear to be refreshing with the new item I put in the
list.

Re: adding items dynamically to ListView
sorry, trying to format that
AjaxLink newIncButton = new AjaxLink(newIncButton){
@Override
public void onClick(AjaxRequestTarget target) {
List list = new ArrayList(bean.getIncList());
Incident inc = new Incident();
inc.setAction(action);
inc.setDescription(whatever description);
list.add(0, inc);

Re: adding items dynamically to ListView
Wicket doesn't allow me to update a ListView object directly through ajax, it
suggests putting it in in a container. So I made a WebMarkupContainer to
wrap the ListView. I have now:
public void onClick(AjaxRequestTarget target)
{
List list = new ArrayList(bean.getIncList());
Incident inc = new Incident();
inc.setAction(action);
inc.setDescription(whatever description);
list.add(inc);
bean.setIncList(list);
listView.modelChanged();
container.modelChanged();
container.setOutputMarkupId(true);
listView.setOutputMarkupId(true);
container.add(listView);
target.addComponent(container);
}
I've confirmed that the model is being updated. The component is still not
being redrawn.

Re: adding items dynamically to ListView
How do you set up the model? Can we see some code?
