Jetspeed

Description:
In Your action class extending JspPortletAction, You have tried to use the setTemplate method, but it did not work. It thrown a NullPointerException in PortletAction when trying to retrieve a “VelocityPortletContext” (how surprising when working with a JSPPortlet)

Cause:
Most common mistake with portlets is to use the hidden action variable and set it to the portlet’s action class:

In the above example, Turbine executes the action before the portlet and therefore the context is null.
