[opencms-dev] NullPointerException - could not be rendered with formatter

[Tobias Herrmann]

Hi Arno,

the exception is caused within the JSP meta-singlelistentry.jsp. There 
you are using a cms:contentaccess tag which throws the null-pointer 
exception. Check how you are using the tag there and verify that all 
attributes have the expected values.

This is not related to the way the formatter is called or the collector. 
 From the stacktrace you can see, that the issue happens when rendering 
a single list entry. So the formatter is called properly and your 
collector is returning at least one result item.

Kind regards,

Tobias
