Need help in refreshing panel..
Hi,
I am facing a problem in refreshing a panel. The requirement is I have a
panel A which has Panel B. Panel A carries list of LDM which is being passed
to Panel B.
public class PanelA {
private LoadableDetachableModelListlt;PostDomain
*detachablePostDomainList *= new
LoadableDetachableModelListlt;PostDomain() {
protected ListPostDomain load() {
return new ArrayListPostDomain();
}
};
public PanelA() {
*this.setOutputMarkupId(true);*
detachablePostDomainList = new
LoadableDetachableModelListlt;PostDomain() {
/**
*
*/
private static final long serialVersionUID = 1L;
@Override
protected ListPostDomain load() {
return new List();
}
};
}
*final PanelB panelB= new PanelB(B,
detachablePostDomainList, PanelA.this);
showPostPanel.setOutputMarkupPlaceholderTag(true);
*
IndicatingAjaxButton ajaxPostSubmitButton = new IndicatingAjaxButton(
submitPost, postForm) {
// some operations
public void onSubmit(AjaxRequestTarget target, final
Form? form) {
if (target != null) {
target.add(PanelA.this);
}
}
};
}
In the above scenario, when I refresh panelA from itself by pressing
ajaxPostSubmitButton, LDM list is getting updated but when I refresh PanelA
from PanelB, nothing happens. What is the reason? I am refreshing PanelA
from PanelB using the same manner.

Re: Need help in refreshing panel..
The problem is now even more complicated as PanelA is not getting refreshed
from PanelB at once. But when I do some operation in PanelB again, PanelA is
then refreshed...
Here is PanelB:
Public class PanelB{
public PanelB(PanelA panelA) {
PostDeleteButtonPanel postDeleteButtonPanel = new PostDeleteButtonPanel(
postDeleteButtonPanel,
postForm) {
protected void
onConfirm(AjaxRequestTarget target) {
try {
// some operation
if (target != null)
*target.add(panelA);*
} catch (Exception exception) {
exception.printStackTrace();
}
}
};
}
}

Re: Need help in refreshing panel..
You have to remember that a LDM is loaded once per request cycle only.
If you change the backing list (e.g. on delete of an item) *after* the
LDM was already accessed (e.g. a link in a ListView), you have to detach
the model once, so it is loaded again:
// some operation calling getObject() on the LDM
...
ldm.detach();
target.add(component)
Hope this helps

Re: Need help in refreshing panel..
Hey...that workedbut still I didn't understand how it worked. I am not calling detach method in ajaxPostSubmitButton of PanelA. So how come it is getting refreshed. I am just trying to understand the concept -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Need-help-in-refreshing-panel-tp4652014p4652018.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Need help in refreshing panel..
It depends whether the LDM is accessed *before* you change something in the backing list. Note that events handled by components in a ListView will trigger loading of the LDM as soon as you access the component's model.
