Thanks, guys. I made this work before the reply emails came, by using reflection, a two dimensional array and a callback object. I didn't have to use rendertool
Thanks again for all the help. - Sriram Gopalan -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Friday, May 12, 2006 12:46 AM To: Velocity Users List Subject: Re: Nested, cartesian loop of dynamic values Claude pointed already in the right direction. Your inquiry is clear enough to give a concrete (untested) code snippet using the RenderTool: #foreach ($function in $functions) #foreach ($parameter in $parameters) $render.eval($ctx, "${object}.${function}(${parameter})") #end #end Your example was missing the object onto which the function is to be applied. The example above has the context object name in the $object context variable. If the $object reference name is known at template writing time, you can use the the reference name directly, but it must be escaped until the eval call: $render.eval($ctx, "\$object.${function}(${parameter})") Cheers, Christoph Sriram Gopalan wrote: > Hi, Here is my requirement.
