[news.eclipse.birt] Re: ODA when scalar is not enough

Daniel,

That is a current design limitation.  One option is to add your 
object(s) to the app context with or without and oda, and then use 
either a scripted datasource written in Java/JavaScript to pull the 
object out and manipulate it.

For that matter you can just use script in a data items oncreate method 
to pull the object out and call a method on it.
