Hi,
I have been having problems with iterations within sub reports within jasper
reports.
I have found the solution to this problem is for ValueStackDataSource to
implement JRRewindableDataSource instead of JRDataSource and implement the
method below.
Could this fix be added instead of me having to add this fix for every new
build.
Many thanks.
David.
implement moveFirst with something like
public void moveFirst() throws JRException {
Object dataSourceValue = valueStack.findValue(dataSource);
if (dataSourceValue != null) {
if (MakeIterator.isIterable(dataSourceValue)) {
iterator = MakeIterator.convert(dataSourceValue);
} else {
Object[] array = new Object[1];
array[0] = dataSourceValue;
iterator = MakeIterator.convert(array);
}
} else {
LOG.warn("Data source value for data source " +
dataSource + " was null");
}
}
