Description Pierre-Alain Blanc CLA 2010-08-20 02:58:36 EDT 
Build Identifier: 2.5.2

When viewing report (either in designer or in birt-viewer), I get a null pointer exception.
According to stack trace, it seems to be caused when trying to localize report variable. Indeed, if I delete the variable, everything is OK.
Note: if I remember well, this error did not happen before I moved some elements (style with map rules) to the library (that is used by my report). I've designed other reports with variables and (same) localization that made no such problems.


Reproducible: Sometimes

Steps to Reproduce:
1. Needs a database that has datamodel which is expected by report
2.
3.

Strangely does *not* happen when exporting to Excel, only when viewing in web-viewer.

Hi,

I noticed there is an error in the trace you attached:
SEVERE: Failed to get the report runnable
org.eclipse.birt.report.engine.api.EngineException: The design file
xxx.rptdesign has error and can not be run.
Which indicates that the design file has errors. Did you notice any errors in
the Problems/Error view?

I've tried a report design using sample db on 2.5.2 release, which is similar
to the attached test report, but can not reproduce the issue you mentioned. 

Is there any chance that you can export the data from db to csv flatfile and
change the report design to use the flatfile datasource?
Comment 5 Xiaoying Gu CLA 2010-08-20 11:30:52 EDT 
Can you reproduce this issue by below steps in your build:
1. New a blank report, using the library file you attached
2. New a variable in the report
3. Preview in webviewer

I can reproduce the NPE(not the same NPE as you attached) in webviewer by above steps in 2.5.2 but not in the 2.6.0 release.

Would you please try the latest 2.6.0 release build to see if it has been already resolved?

Hi !

Thanks for the investigations.
I've tried the same report under runtime version 2.6.0 and couldn't reproduce it. Seems that the bug was fixed between 2.5.2 and 2.6.0

As it seems to work also when generating Excel under 2.5.2, it is fine for me. You can close the bug. Thanks again for your support !
Comment 7 Xiaoying Gu CLA 2010-08-23 22:21:06 EDT 
Fixed in 2.6.0 release.
