I hope someone can help me with this.
I am creating a report with a sub report. I have a to-many relationship like
this:
project to-many projectSteps
since I wanted to print a project with the steps ordered by its dueBy date, I
created:
public JRBeanCollectionDataSource theSteps() {
return new JRBeanCollectionDataSource(
ERXArrayUtilities.sortedArraySortedWithKey(this.projectSteps(), "dueBy") );
}
This worked beautifully. I could print to JasperReports and each row of
projects would print its steps ordered by the date.
But now, if I try to print the report, it prints once and hangs if I try to
print it again.
At first I thought that this was acting as if I had a problem with a second
thread was trying to access my EOs. Except I am using ERJasperReports and it
carefully creates a new editingContext each time it is run. My next experiment
was to delete the subReport from my report and now it prints multiple times
with no problem.
So I put the subReport back, and changed my method. I eliminated the above
method (theSteps()) and instead just used the relationship as a field. I wanted
to prove that my method that is returning the JRBeanCollectionDataSource was
not the problem. So I created a field in iReport so correspond to the
relationship.
So now I am using only the EO and its relationship pieces.
It fails exactly the same. It appears to fail in ERJRFoundationDataSource's
next() method. ERJRFoundationDataSource implements JRDataSource.
I am at a loss. Since each iteration uses a new editingContext in a new thread,
why is this failing? I want to cry.
I hope someone can help.
