Passing a collection to subreport

2006-02-24 09:23

hello,

I am trying to pass a javabean collection to master report which contains three attributes, name, ssn and children details(which is a collection again).

 

I wanted a report like

Name SSN

Subreport : childName, childSSN

childName, childSSN

 

I can pass a collection to the master report but from there how can i pass one of the fields of each bean (which in-turn is a collection) to the subreport ?

 

When i try this, i get a classcastexception (ArrayList)... because the child collection is an arraylist.

 

thanks for any help

Well, something is wrong is iReport. When i tried with a java program (compiling and passing the Bean collection) it worked, somehow iReport needs a seperate connection to each of the report (master and sub) !!

 

Connection (not to database) but to a datasource's Static getter method that returns a collection.

Ok, i got rid of ClassCastException by doing a new JRBeanCollectionDataSource($F{beanCollection})

 

but the subreport is not recognizing the beans fields in the collection.

 

It says, no getter method for field Name, but actually there is !
