Re: / /OREF:CPT482FF Velocity context: portlet variable is null?

[Todd Kuebler <tk...@cisco.com>]

the guru's correct me if I'm wrong, but the context seems to be empty if 
you have defined the action class in the submit form.  The reason this 
occurs seem to be that this triggers _turbine's_ action handling (which 
doesn't create a context) instead of the Velocity Portlet handling the 
action (which does create the context).  See if you have defined

<input type="hidden" name="action" value="<your action class>">

in your submit form html, that was my problem when I had this issue.
