[news.eclipse.birt.usability] IllegalStateException when attempting to p

[rlewelly@xxxxxxxxxx (Rob )]

I am having a problem generating a simple report in BIRT. I successfully 
created my Data Source (Oracle), my Data Set, and I have copied the data 
fields into my form.  But every time I attempt to preview the report, 
receive the following exception: 

java.lang.IllegalStateException: The viewing session is not available or 
has expired.

I am using Eclipse version: 3.4.2, BIRT version: 2.3.2.1

Any help would be greatly appreciated. 

Thanks.  

Rob


The full exception follows:


java.lang.IllegalStateException: The viewing session is not available or 
has expired.
