Hi, I went for customizing the Location page,
generated a pages/show/LocalityShow.java and .tml
the tml I copied it from the Show.tml file
and the .java I overrided the following methods:
public Class<Sucursal> getType() {
> public Link onActionFromDelete() {
> public boolean isAllowRemove() {
>
the result is that after I create a new Locality, it forwards to the show
locality page but before rendering this error shows up:
org.apache.tapestry5.internal.services.RenderQueueException
