The error is triggered by OpenCms when initializing the "formatter" taglet
of your published "/system/modules/org.my.template/formatters/footer widget
formatter.jsp". In Java, the stacktraces are written from the innermost
invokation to the outtermost:

This is the error message:

>
> May 07, 2015 10:50:41 AM org.apache.catalina.core.ApplicationDispatcher
> invoke
> SEVERE: Servlet.service() for servlet jsp threw exception
> org.opencms.main.CmsException: Error while reading element bean from
> request

Triggered by:

        at
> org.opencms.ade.configuration.CmsADEManager.getCurrentElement(CmsADEManager.java:337)
>

...that was called here:

        at
> org.opencms.jsp.CmsJspTagFormatter.init(CmsJspTagFormatter.java:230)
>

..and 'init' was invoked here:


>         at
> org.opencms.jsp.CmsJspTagFormatter.doStartTag(CmsJspTagFormatter.java:128)
>

...and this was invoked by your jsp code:

        at
> org.apache.jsp.WEB_002dINF.jsp.online.system.modules.org_my_template.
>
> formatters.footer_002dwidget_002dformatter_jsp._jspx_meth_cms_005fformatter_005f0(footer_002dwidget_002dformatter_jsp.java:109)


Apache Tomcat compiles the jsps into classes in a predefined directory,
usually resulting in the namespace prefix 'org.apache.jsp.WEB_002dINF.jsp'.
The rest of the namespace identifies where is the jsp stored.

In this case:
   online -> online version
   system.modules.org_my_template.formatters ->
system/modules/org.my.template/formatters
   footer_002dwidget_002dformatter_jsp -> "footer widget formatter.jsp"
