test case

Hi,
First of all, this is the first time I use a *Joint DataSet*, 
I thus apologize if I did something wrong.


Steps To Reproduce:
1. Create 2 datasets.
2. create a *Joint DataSet* using those" 2 Datasets.
3. Add log information on different available events (beforeOpen, afterOpen, beforeClose, afterClose).
4. DataSet Close events don't seem to be called.

Tested with Birt 4.4.2 and 4.5.0.

I attached a sample (*be careful*, absolute paths have been set to the csv datasources).
The four available events contain a _System.out.println_ call (fell free to change this as a more convenient way).

Running this report using _Birt RCP Designer_, the _command line_ or even _programmatically_ results to only the following logged lines

* opening data1Set
* opening data2Set
* data1Set opened
* data2Set opened

No information on dataset closing events.


The main (and *critical* IMHO) issue with this (if confirmed), when using real datasets (I mean targeting databases, Oracle in my environment), is this results in _too many cursor opened_ 
as my *joint dataset* is included in a table, and thus played many times (that's why the sample I provide here contains a table embedding my script dataset).


+Note+: I apologize for my poor English skill, I'am French ;-)

Any help will be appreciated.

Thanks,
Nicolas
