Can I use a Field as a datasource?

[tedpet5]

I am passing data to my jasperreport from my webapp. Each object is in the form of:

{

description String

usename String

steps array of strings

theDate date

}

those objects are my Fields 

In the iReport manual, it only mentions using parameters as a datasource.

Can I safely use a Field as a datasource to pass to a subreport or a list element?

new JRBeanCollectionDataSource($F{steps})

sure. if your datasource really delivers a collection of collections, or at least one element of your fields is a collection of beans, then you can use that field to create a new bean datasource.

otherwise it won't make sense.
