Question

I’m trying to build a gmail contextual gadget.
I had it working in the past but i must of changed something and it does not work now.
I have created the listing successfully and added the gadget to a test domain of mine.
But still nothing happens when i open up an email.

this is the manifest:

<?xml version="1.0" encoding="UTF-8" ?>
<ApplicationManifest xmlns="http://schemas.google.com/ApplicationManifest/2009">
  <Support>
    <Link rel="manage" href="http://example.com" />
    <Link rel="support" href="http://example.com" />
    <Link rel="deletion-policy" href="http://example.com" />
  </Support>

  <Name>Clarizen</Name>
  <Description>Integrate with clarizen</Description>
  <Extension id="navLink" type="link">
    <Name>Clarizen</Name>
    <Url>http://example.com</Url>
  </Extension>

<!-- EXTRACTOR -->
<Extension id="Ex1" type="contextExtractor">
  <Name>Ex1</Name>
  <Url>google.com:EmailBodyExtractor</Url>
  <Triggers ref="gadget1"/>
  <Scope ref="emailBody"/>
  <Container name="mail"/>
</Extension>

<!-- EXTRACTOR -->
<Extension id="Ex2" type="contextExtractor">
  <Name>Ex2</Name>
  <Url>google.com:SubjectExtractor</Url>
  <Triggers ref="gadget1"/>
  <Scope ref="emailSubject"/>
  <Container name="mail"/>
</Extension>

<!-- GADGET -->

<Extension id="gadget1" type="gadget">
  <Name>Clarizen contextual gadget</Name>
  <Url>http://example.com:2057/test.xml</Url>
  <Container name="mail"/>
  <!-- Uncomment this to enable Caja. -->
  <!-- <Param name="caja" value="enabled"/> -->
</Extension>

<!-- SCOPE -->

<Scope id="emailSubject">
  <Url>tag:google.com,2010:auth/contextual/extractor/SUBJECT</Url>
  <Reason>integaret with clarizen</Reason>
</Scope>

<Scope id="emailBody">
  <Url>tag:google.com,2010:auth/contextual/extractor/BODY</Url>
  <Reason>integaret with clarizen</Reason>
</Scope>

</ApplicationManifest>

I am able to load http://example.com:2057/test.xml in igoogle so i think the problem is with the manifest.

What can the problem be and how can i validate the manifest file and trouble-shoot this sort of problem.

Thanks

finally i found out the problem – you cannot use the same gadget spec twice.
So i made a fresh copy of the gadget spec – http://example.com:2057/test_V2.xml,
and that got it working.
See http://code.google.com/apis/gmail/gadgets/contextual/ at the paragraph “Reusing a gadget spec”
