How to use Map as dataset element in JasperReports?

[grzegorz.ziemonski]

I'm passing a parameter to Jasper which is a collection of Maps. I would like to use this collection as dataset for a table.

If I had a collection of normal Java objects I would do:

$F{description}[/code]

to get the field. I would like to do something like:

this.get(description)[/code]

or

this.values().get(1)[/code]

Is it possible to retrieve a map value in a table like this?
