basicly I have a datasource and want to calculate something fomr the given
result.
so I tried with a simple wrapper object and getting always this exception.
I know there is nothing null and i put the classes under:
C:\development\eclipse\plugins\org.eclipse.birt.report.viewe r_2.1.0.N20060415-1243\birt\WEB-INF\lib
so what do I do wrong?
org.eclipse.birt.data.engine.core.DataException: The data type of computed
column "ttt" is org.eclipse.birt.core.data.DataType$AnyType, but one of
its value is "null", which cannot be converted to
org.eclipse.birt.core.data.DataType$AnyType.
