| How to avoid script evaluation errors on empty data sets [message #190855] |

I have a report I want to adjust when a subsection has no data in the
data set. I have set "visibility rules" using the Total.count() function.
However, the sections have headers/footers that analyze the data using
Total.sum(), Total.min(), and Total.max() and it appears these scripts
are run even when the "visibility rules" turn off the display of the
results. I think this may be due to the two-pass generate / present
lifecycle of a BIRT report.
How do I turn off these calculations? Is there a rule to apply (Map)?
Do I need to code the Total.count() condition check into the script? If
so, could someone provide an example?
Thanks for your help,
- Jim
P.S. In reviewing the newsgroup, I noticed a similar post by Catalina
on 9/13/2006.

Okay, as always, when you ask a question to a newsgroup you get prepared
to answer questions. I forgot an important detail that I went back to
document - namely, the problem only arises when I am running the reports
from my Tomcat server and not from within Eclipse BIRT.
In the process of getting prepared, here's what I found:
* When I run the report from Eclipse, the URL used to launch the report
(linked from a summary report) starts http://<host:port>/viewer/run?......
When I run the report from my Tomcat server, the URL used to launch the
report starts http://<host:port>/viewer/frameset?.....
* The report has no Table of Contents.
The problem only arises in the viewer/frameset?.... launch of the report
which occurs when the summary report is launched with frameset.
So, I know how to fix the problem in the short term but not really the
underlying cause of the problem. I am going back to read the newsgroup
entries under the frameset threads.
I would be interested in anyone's explanation of the difference and
whether this should be entered as a bug against BIRT's runtime viewer.
The power of "news group" therapy ;-)
