Re: Zone error after I have updated to Tapestry 5.2.6
The error looks a lot like what you get when you are expecting an Ajax request (and so return a Block), but instead get a regular page request where you would want to return null or a Page. As a general practice, try to allow for graceful degradation in the absence of javascript by doing the check " if (request.isXHR()) " before returning a block or zone body. I've been surprised a couple of times. I hope that helps. Regards, Jonathan On Thu, Sep 8, 2011 at 12:31 PM, Javicha wrote: > no, that's not the error.

Re: Zone error after I have updated to Tapestry 5.2.6
no, that's not the error. All is well defined. I have declared the zone: And the actionlinks refer to this zone: href="#" t:type="ActionLink" t:id="previousPatientLink" t:zone="searchPatientResultZone" href="#" t:type="ActionLink" t:id="nextPatientLink" t:zone="searchPatientResultZone" As I said before, this worked before the upgrade.

Re: Zone error after I have updated to Tapestry 5.2.6
I don't see a zone parameter in your code.
I started tapestry with 5.2, so I don't know upgrade issues,
but I do know that the element which has zone.getBody() returning from it
has to have a zone= parameter in its tml.

Re: Zone error after I have updated to Tapestry 5.2.6
no, that's not the error. All is well defined.
I have declared the zone:
And the actionlinks refer to this zone:
#
${message:link-previous}
#
${message:link-next}
As I said before, this worked before the upgrade.
I have not changed any .java and .tml files.

Re: Zone error after I have updated to Tapestry 5.2.6
my guess you are missing zone= parameter in one of your tml files.

Zone error after I have updated to Tapestry 5.2.6
Hi!
I was working with Tapestry 5.1.0.5 and everithing worked fine. I updated to
Tapestry 5.2.6 because new project needs, and now I have problems with
actionlinks.
The case is the following:
I use paging for searches. In the search result page, I have two actionlinks
(previous and next links) that make a new search and re-load the zone with
search results. The code of a link is:
public Object onActionFromNextPatientLink() {
if (patientBlock.isHasMoreElements()) {
startIndex += PATIENTS_PER_PAGE;
patientBlock = coreFacade.findPatient(obtainFilter(),
startIndex,
PATIENTS_PER_PAGE);
return searchPatientResultZone.getBody();
} else {
return null;
}
}
After Tapestry update, I have the follow error when I click a actionlink:
"A component event handler method returned the value Block[Body of
patient/Find:searchpatientresultzone, at
classpath:es/clinica/enkeli/core/interfaces/web/pages/patient/FindPatient.tml,
line 60]. Return type org.apache.tapestry5.internal.structure.BlockImpl can
not be handled."
And the console notes the following line of code as the source of the error:
#
Debugging I saw that the problem was the line "return
searchPatientResultZone.getBody();"
There is a problem with Zone in this Tapestry version? This error has me
puzzled!
Thnaks for help!!
