Subreport with ArrayList of Strings as Datasource?

[Layna]

Hello :).

I've got a subreport that receives an ArrayList<String> as datasource.

I am using IReport to create the Reports, and had been hoping to reach the elements of the Array by just puttign "this" as fielt into the detailBand.

Unfortunately: No success.

How do I get my Strings, then?

I think you can't do that this way.

So make a wraper class and put a string field in it, and then you can acces the String via $F{yourString}

I did something similar some months ago...but I can't find the report (guess it was at some customer)...

 

so when I remember right it was something like this for datasource-expression:

 

Code:

new JRMapArrayDataSource($F{YourFieldOfTypeArrayList}.toArray())

 

Be sure, that your field holding the strings is of type java.util.ArrayList

 

should work!!!! :-)
