Hallo,
I have question about the work with array.
I have a #for-loop in my template like this:
#foreach ($column in $column-detail-data)
"${column.getChild("header").Text}",
#end
and I want to now if I'm on the end of the array $column,
because of the comma at the end of the command.
If there is no more elements, I don't want to set comma any more.
Can you give me some advice please?
Thanks for reply.

The simplest solution is to prefix the comma:

#set( $sep = "" )
#foreach ($column in $column-detail-data)

$sep"${column.getChild("header").Text}"

#set( $sep = ", " )
#end

This is fully independant of any counter and end of array.

Christoph's simplest solution works perfectly :)
but if you want to separate each column with , and the last one with
"and" here is a way to do it
Example: "java","perl","c++" and "xul"
more complicated though

#set( $len = $column-detail-data.length )
#foreach($column in $column-detail-data)
#set( $velocityCount2 = $velocityCount + 1 )
#set( $len2 = $len - 1 )
"${column.getChild("header").Text}"#if ($len2 == $velocityCount)
and#elseif ($len $velocityCount2),#end
#end
