RTFM...
if the reference
  $billgrp
in the template emits
  Billgrp1:[12,13,15,17]
to the output, then your orbject is somewhat strange.
a) billgrp is a special object, and probable has a custom toString()
   method velocity is then using.
b) OTOH, as the name is implying... each $billgrp is probably a
   group itself?
   So you might need an inner loop or use specific accessor methods
   to get parts of it.

You can try to find out more about your object by debugging it placing
  $billgrp.class.name
in the template.

Then look at the ApiDoc or the interface description for that class.

Also note that velocity allows ranges in the foreach:
#foreach ($billgrp  in $additionalorder.getBillGroupIdDisplay())
  #foreach( $i in [0..1] )
   #set( $index1 = ${velocityCount} + 1 )
Billgrp${index1}: $billgrp.getXYZ($i)
  #end
#end

Hope this helps you to deeper understanding,
Christoph

Hi All,

I have a problem in velocity any help on this greatly appreciated.


\begin {tabular} {ll}
#foreach ($billgrp  in $additionalorder.getBillGroupIdDisplay())
$billgrp
#end
\end {tabular}

in the above code $additionalorder.getBillGroupIdDisplay is a List and $billgrp displays a list of values like [12,13,15,17] but I want to display only first two values in the list and not all.

My expected output is :
Billgrp1:12
Billgrp2:13

my current result is Billgrp1:[12,13,15,17]

I aslo tried with $billgrp.get(0) to get first element and this is not working in Velocity.

Thanks  & Regards
Venkat
