Disabling BIRT dataset caching in RCP..

I am creating an .rptdesign in RCP and I have been noticing that BIRT datasets are cached ie they do not refresh every time and birt thinks that the data set is the same. 
 
Anyone knows how I can disable the dataset caching in BIRT RCP? The only 'cure' to this dataset problem that I have found is restarting the entire Eclipse. 'Clean Project' and 'Refresh (dataset)' do not work....
 
Any ideas to get past this hump?
Thanks!!

Can you provide some more details?
 
What type of data source are you using for the data set?
When you say it is caching, are you referring to when previewing the data set or running the report?

I am using POJO datasource that produced hard coded dataset.
I observe caching when I preview the dataset in the birt previewer and when I run the report through RCP as well.
 
For example:
At time=t_0:
I hard code my .jar to produce a dataset that has: `1,2,3`
I name the jar as A.jar
In birt RCP, I create a pojo dataset, link to A.jar and make a dataset out of it
when previewing I see `1,2,3`
 
At time=t_1:
Now I decide that my dataset should have '7,8,9'
I change my A.jar to produce a dataset that has: `7,8,9` 
I name it B.jar
In birt RCP, I change a pojo dataset from A.jar to B.jar and make a dataset out of it
when previewing I still see `1,2,3', although I should be seeing '7,8,9'

Interesting, do you have time to create the A.jar and B.jar examples you have described so I can use them for testing?
 
Let me know if not and I can see about finding some time to whip these up to use to reproduce the issue.
