A problem occur at loop of zone
First show my test code
test.tml
${str}
delete
test.java
public class Test {
@Property
@Persist(PersistenceConstants.SESSION)
private List strs;
@Property
private String str;
@Property
private int index;
@InjectComponent
private Zone testZone;
void setupRender() {
strs = new ArrayList();
strs.add("1");
strs.add("2");
strs.add("3");
strs.add("4");
strs.add("5");
}
Zone onActionFromDelete(int index) {
System.out.println(index);
strs.remove(index);
return testZone;
}
}
I click the "delete" actionlink is right,the Zone updated,
but I click the "delete" actionlink,the page refreshed,and my console show
the warn log
"2011-07-12 09:54:55,265 [ComponentInstanceResultProcessor] WARN

This happens when a non-AJAX request is made and an AJAX event handler
method value is returned.

I according to your issue,
public class Test {
@InjectComponent
private Zone testZone;
Block onActionFromDelete() {
return testZone.getBody();
}
}
but occur the exception like this
A component event handler method returned the value Block[Body of
test/Test:testzone, at classpath:com/lai2/pages/test/Test.tml, line 21].
Return type org.apache.tapestry5.internal.structure.BlockImpl can not be
handled.

Re: A problem occur at loop of zone
Posted by dick_hu <di...@gmail.com>.
this problem I still have not sovle.
But I use MultiZoneUpdate as return type it runs success.
I guess Is the actionlink inside in the zone,when the zone updated cause the
actionlink's ajax action invalid.
can you help me? I write a easiest test,but failure yet.
test.tml
<t:zone t:id="testZone">
<t:actionlink t:id="delete" zone="testZone">
delete
</t:actionlink>
</t:zone>
test.java
public class Test {
@InjectComponent
private Zone testZone;
Zone onActionFromDelete() {
return testZone;
}
}

Re: A problem occur at loop of zone

For some reason your request is not being submitted as an ajax request. You
can verify it by
@Inject
private Request request;
@Inject
private Logger logger;
void onYourEventHandler(){
logger.debug(request.isXHR());
}
This may be because of a JavaScript error, so try debugging through firebug
or chrome

The template is not visible, are you using zone parameter of actionlink(you
should prefer eventlink over actionlink). Only then will the request be ajax
based.
