Error in accessing "parameter" from JSP Page,
August 19, 2009 at 12:34 PM

I can see proper value of "parameter" getting calculated by the Controller form which implements Dispatch Action.

But when im using "parameter" from the corresponding JSP Page, an Error is thrown, indicating "NULL property value" for "Parameter"...

Can anyone help ???
