ReportServer: java.lang.string error with BIRT report.
Posted 20 April 2011 - 05:30 AM
I’m running reports based on BIRT in the ClearQuest Report Server(v.126.96.36.199), which are being designed in Rational ClearQuest RCP Designer(version: 7.1.1, build: 7.1.1.D091201A). I can work and run these reports into RCP Designer, however when I upload these ones to the report server and run them, I obtain the following message:
The data type of computed column <computed_column_name> is java.lang.String, but one of its value is "null", which cannot be converted to java.lang.String.
I’ll appreciate if anybody could help me with this. If more information is necessary, please let me know.
Thanks a lot and have a great day!.
