Yeah, it's easy! Thanks!
Well, there is some things i wanna know...
1 - I figured it out that i don't need to write JSON as response for the
even handling... Just returning the Zone's Body to magically refresh it is
all i need (since the Grid knows how to build itself). But this code isn't
working (sorry for the portuguese code, but i believe it's readable):
@InjectComponent
private Zone zoneMapa;
@Log
@CommitAfter
public Block onGravarPoi(String nomePoi, String telefonePoi, String
posXPoi, String posYPoi)
{
// code
return zoneMapa.getBody();
}
The ajax call looks like this (using jquery):
$j.ajax({url: urlGravarPoi});
Do I need to change something?
2 - I did something like this to get the XHR URI in the JS:
**** Page class ****
@Inject
private ComponentResources componentResources;
public String getUrlGravarPoiXHR()
{
return
componentResources.createEventLink("gravarPoi").toAbsoluteURI();
}
**** Page template ****
<t:hidden t:id="urlGravarPoi" value="prop:urlGravarPoiXHR" />
**** Map's JS event handling ****
var urlGravarPoi = $j("input[name=urlGravarPoi]").val(); // and some
workaround to append the context
$j.ajax({url: urlGravarPoi});
Well, I just wanted to see it working and obviously that part isn't nice...
Now, what's the best way for that? I didn't understand how the
Autocomplete's mixin (the example from the tap site) uses the RenderSupport
to pass the link to the js.
Thanks for the reply! Any more help would be appreciated :)
