Re: [Portal] Why don't cocoon errors appear in a coplet ?

[Olivier Billard]

Hi Carsten,

Thanks for your answer.
For some of our pipelines, we don't use the cocoon protocol, but just a serverpages 
generator. Renaming a variable in the XSP to cause a "Language Exception" page, I still 
have the content of the coplet empty (but as before the decoration remains : <title>My 
title</title>). And I still have the "correct" error display when calling directly the 
coplet pipeline.

I added
  <attribute>
    <name>error-uri</name>
    <value
      xsi:type="java:java.lang.String"
      
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";>cocoon:/erreur-coplet</value>
  </attribute>
in the profiles/copletdata/portal.xml in my coplet and added
a match in the sitemap, in the very beginning to avoid */**-like matchings :
  <map:match pattern="erreur-coplet">
    <map:generate type="notifying"/>
    <map:transform src="stylesheets/system/error2html.xslt">
      <map:parameter name="contextPath" value="{request:contextPath}"/>
      <map:parameter name="pageTitle" value="Resource not found"/>
    </map:transform>
  </map:match>
but I have the same result : the content of the coplet is void, and it seems that this 
pipeline is never called.

But it's right that the portal uses the cocoon protocol to aggregate the various coplet 
contents. But why doesn't it detect map:handle-errors branchings ?

Hi,

the answer isn't related to the portal but to the Cocoon sitemap
engine: The portal uses internal pipeline calls (cocoon: protocol).
Whenever Cocoon uses an internal pipeline call, the error handler
of that pipeline is never invoked, so if you do a
<map:generate src="cocoon:/my-pipeline"/>

and there is an error in your "my-pipeline", the error handler
of "my-pipeline" is never invoked. In the case above the 
error handler of the pipeline containing the map:generate is
invoked.

In the case of the portal, the error is "ignored". You can specify
for each coplet an alternative pipeline that is invoked if the 
real content pipeline throws an error. Have a look at the
configuration of the coplet showing my weblog. That coplet shows
the "real" content from the net if you have a network connection,
if not a static (old) xml file is read.

Subject: [Portal] Why don't cocoon errors appear in a coplet ?
Hi cocooners !

I posted in the users' but maybe some sitemap gurus can show 
me the light ;).

I use the portal for a project and i'm not able to display 
errors in a (main) coplet.
I always have a blank content, as if when rendering the 
content of the coplet, the error content is not put in the 
whole portal page.

I tried xml-serializing, html-serializing errors :

    <map:handle-errors>
      <map:select type="exception">
        <map:when test="not-found">
          <map:generate type="notifying"/>
          <map:transform src="stylesheets/system/error2html.xslt">
            <map:parameter name="contextPath" 
value="{request:contextPath}"/>
            <map:parameter name="pageTitle" value="Resource 
not found"/>
          </map:transform>
          <map:serialize status-code="404"/>
        </map:when>

        <map:when test="invalid-continuation">
          <map:generate src="not-found.xml"/>
          <map:transform src="welcome.xslt">
            <map:parameter name="contextPath" 
value="{request:contextPath}"/>
          </map:transform>
          <map:serialize status-code="404"/>
        </map:when>

        <map:otherwise>
          <map:generate type="notifying"/>
          <map:transform src="stylesheets/system/error2html.xslt">
            <map:parameter name="contextPath" 
value="{request:contextPath}"/>
          </map:transform>
          <!--map:serialize status-code="500"/-->
--->      <map:serialize type="html"/>
        </map:otherwise>
      </map:select>

    </map:handle-errors>

(map:otherwise is choosen, i tried renaming the transformer 
src attribute)

But no way : I have no content in the coplet...
I can right display the error when calling the coplet pipe, 
but it' empty in the portal page...

It seems to work like standard/error output : when an error 
occurs, the standard sitemap output is empty, and the sitemap 
error output contains the error catched in the map:handle-errors.

Thanks in advance for your answers !
