Hi,

I am using the visibility option to hide elements on some of my reports and it works fine in the Birt report viewer but when I try to export as Excel. I get a NullPointerException see error below.

Configuration:
Version: 6.6.0
Build id: 6.6.0-20081015

Please let me know if there is a work around for this.

Plus it looks like sometimes not all tables are displaying when exporting as PDF if the report containing multiple tables.

I would appreciate any help.

Thanks and regards,

Maturin,
I believe this is a known BIRT issue.
http://dev.eclipse.org/newslists/news.eclipse.birt/msg24426.html

You could upgrade to MyEclipse 7.0 and try this since MyEclipse 7.0 integrates the latest version of BIRT.

Thank you very much Nipun, upgrading to MyEclipse 7.0 fixed the problem!!
