Hello

I am working on an helpx.adobe article about CQ5 work flows . I am posting the link for your reference.

https://helpx.adobe.com/experience-manager/using/invoking-experience-manager-workflows-using.html

The problem is I am not getting any mails to adminstrator to complete the work flow. Even I have tried different workflow excersice with mail sending task but getting the same error I am pasting lines from my log file. Kindly look into this and provide me with the fix.

I have gone through the article - it works - I also tested on AEM 6

Here is the page that invokes the Workflow:

[img]WOrkflowAPI1.png[/img]

Once it invokes the workflow via  the WOrkflow API - the message is in the admin queue - as shown here:

[img]WOrkflowAPI2.png[/img]

Ensure that you are referencing the correct workflow model name in the example JSP - check the path here:

/etc/workflow/models

Here is the name of the workflow model:

The issue is AEM cannot find the content at /libs/cq/workflow/content/inbox/list.json:

06.04.2015 21:19:30.917 *ERROR* [127.0.0.1 [1428335370884] GET /libs/cq/workflow/content/inbox/list.json HTTP/1.1] org.apache.jsp.libs.foundation.components.primary.cq.Page.wfsummary_json_jsp resource has no content. path=/libs/cq/workflow/content/inbox/list.json referrer=null

I will take a look here and see if I can reproduce your issue.

@Scott

 

I have tried more examples on workflow models which contains participant step. But I am getting the same error when clicking on admin inbox.

Please take a look and help me on this. Thanks alot for your support
