double parsing

[Demetz Markus <e9...@student.tuwien.ac.at>]

hello,

i'm very new to velocity
i want to do a think like following:

my context looks like this:

context.put("name1", "something"),
context.put("name2", "somethingelse"), ...

my temlate has a loop:
#foreach($record in $list)
	$name$velocityCount
#end

the result only is $name1 $name2 but I would like to have the context of
$name1 $name2 -> something and something else...
is this possible?

very thanks

You can do this with the eval method of the RenderTool.

http://jakarta.apache.org/velocity/tools/javadoc/org/apache/velocity/tools/generic/RenderTool.html

However, you might be better off changing the data struture(s) that you're 
putting into your context rather than building variables in the template.

For example, put the names in a map with the $record as a key, or create a 
new data struture that contains both record and names and put them in a 
list, or just put the names in a list.
