Does chart engine support joined data set [message #189158] Fri, 01 September 2006 15:14
Eclipse UserFriend
Originally posted by: lingtai.earthlink.net

I have successfully joined two data sets. But, when I select the joined
dataset as the selected dataset for a line chart, I got an exception. I
am using BIRT 2.1, does BIRT 2.1 chart engine support joined data set?

Many thanks,
Ling

The error I received is:
> $NO-RB$ Data engine operation failed due to an unexpected exception.
