Subject NullPointerException in trinidadinternal [TRINIDAD]
Date Mon, 25 Oct 2010 00:06:22 GMT
Hi,

 

I have been searching the forum but haven't found any hints on what's wrong
and the reason why this exception is thrown. 

The example I provided is cut down to the basics. An action returning null
or "" should be possible right?

 

I would really appreciate if someone could take a look into this. Thanks!
