Hi,
I have a template wich look like this one :
...
<t:grid source="clients" row="client">
<t:parameter name="nameCell">
<t:actionlink t:id="clientLink" context="client.id"
zone="clientZone">${client.name}</t:actionlink>
</t:parameter>
</t:grid>
<t:zone t:id="clientZone"/>
<t:block t:id="clientBlock">
<t:grid source="selectedClient.mailingsList" row="mailing">
<t:parameter name="titleCell">
<t:actionlink t:id="mailingLink" context="mailing.id"
zone="mailingZone">${mailing.title}</t:actionlink>
</t:parameter>
</t:grid>
<t:zone t:id="mailingZone"/>
</t:block>
<t:block t:id="mailingBlock">
<t:beandisplay object="selectedMailing"/>
</t:block>
...
and the associated code :
public class Clients {
@Inject @Service("mailingServices")
private IMailingServices mailingServices;
@Inject
private Block clientBlock;
@Inject
private Block mailingBlock;
@Property
private Client client;
@Property
private Mailing mailing;
@Property @Persist
private Client selectedClient;
@Property @Persist
private Mailing selectedMailing;
@OnEvent(component="clientLink", value="action")
private Block actionFromClientLink(Long id) {
selectedClient = mailingServices.loadClient(id);
return clientBlock;
}
@OnEvent(component="mailingLink", value="action")
private Block actionFromMailingLink(Long id) {
selectedMailing = mailingServices.loadMailing(id);
return mailingBlock;
}
}
and i get the exception :

If i move my zone 'mailingZone' outside from the clientBlock, everything
works fine ...
Is there a way to implement "dependent" zones (i mean zone inside zone
inside zone ...) ?
Thanks in advance.
