Re: Using DataView newItem method to display a BreadCrumbPanel

2011-02-03 Thread msj121 

Well if you have the Panel

Panel pnl = new Panel("breadcumbholder");
pnl.setOutputMarkupId(true);

and if this panel is made global, then you can add it inside other classes
if necessary target.addComponent(pnl);

This way you only update the panel and not the entire page

I seemed to have resolved the issue by adding the page that owns the bread
crumb panels as the
Ajax target; I do this within the BreadCrumbPanel create method:


getPage().setOutputMarkupId(true);
target.addComponent(getPage());

Thanks for the reply Matthew. Unfortunately, I'm not sure how to pass the
panel to the target.
Putting it within the IBreadCrumbPanelFactory create method seems to have no
effect.

Re: Using DataView newItem method to display a BreadCrumbPanel

2011-02-01 Thread msj121 

not sure what activate does, I would hope though that it would add the object
to a panel on the page, and then you call "target.addComponent();" As
this target (the AjaxRequestTarget) deals with actually updating the front
end of the page.

Also Data Repeaters are somewhat dubious in that they refresh their content
on each reload, so don't try to add the content to the DataView itself
(which I assume you are not). Similarly using the model and not the value of
the model might cause some issues, I am not sure. The stack error trace
after this first visual issue is fixed would be useful.

I do presume they are somewhat separate (ie: fixing one won't solve the
other).

Using DataView newItem method to display a BreadCrumbPanel

2011-02-01 Thread shetc 

Hi All,

I am trying to add an onclick event to a table row -- each row is created
using a DataView.
To make an entire row clickable, I add an AjaxEventBehavior via the
DataView's Item newItem method.
This seems to work as far as an onEvent event being raised when I click on a
table row.
However, I am trying to activate a BreadCrumbPanel from within the onEvent
event. Nothing seems
to happen as far as showing the next panel (called JobDescPanel). If I click
on the row again
then a component not found on page exception is thrown. I have supplied a
snippet of code below.
Is it wrong to try and activate a breadcrumb from this Ajax event?

Thanks,
Steve

P.S. Using Wicket 1.4.10


private void buildDataView() 
{
final DataView dv = new
DataView("dataView", jsdp) {
private static final long serialVersionUID = 1L;

@Override
protected Item newItem(String id, int 
index, final
IModel model) {
Item item = super.newItem(id, 
index, model);
item.add(new AjaxEventBehavior("onclick") {
private static final long 
serialVersionUID = 1L;
@Override
protected void 
onEvent(AjaxRequestTarget target) {
activate(new 
IBreadCrumbPanelFactory() {
private static final 
long serialVersionUID = 1L;
public BreadCrumbPanel 
create(String componentId, IBreadCrumbModel
bcm) {
JobSearchResult 
jsr = model.getObject();
return new 
JobDescPanel(componentId, bcm, homePage,
jsr.getOrderId());
}
});
}
});
return item;
}

...
}
