So I've made progress but am stumped. I created a customcomponent and used a
rule to make one of the displayPropertyKeys a hyperlink.
I am basically using the JasperReportExample. I created a hyperlink as one of
the property keys. this will fire off the method that starts the jasper reports
process:
public WOActionResults printBrief() {
Brief theBrief = (Brief)object();
Callable<File> reportTask =
Reports.createBriefReportTask(theBrief);
CCAjaxLongResponsePage nextPage =
pageWithName(CCAjaxLongResponsePage.class);
// Push the task into the long response page
nextPage.setTask(reportTask);
// Controller for handling the Callable result in the long
response page
FileTaskDownloadController nextPageController = new
FileTaskDownloadController();
// Hyperlink text on the "Your file is downloaded page" to get
back here
nextPageController.setReturnLinkText("Reports Menu");
// The filename for the download
nextPageController.setDownloadFileNameForClient("BriefReport.pdf");
nextPage.setNextPageForResultController(nextPageController);
NSLog.out.appendln("*** nextPage = ***** " + nextPage);
return nextPage;
}
Here is the Reports method:
public static Callable<File> createBriefReportTask(Brief b) {
String reportDescription = "Printed Brief";
HashMap<String, Object> parameters = new HashMap<String,
Object>();
parameters.put("reportDescription", reportDescription);
parameters.put("userName", "User From session");
EOQualifier qualifier = ERXQ.equals(Brief.JOB_NUMBER_KEY,
b.jobNumber());
ERXFetchSpecification<Brief> fs = new
ERXFetchSpecification<Brief>(Brief.ENTITY_NAME, qualifier, null);
ERJRFetchSpecificationReportTask reportTask = new
ERJRFetchSpecificationReportTask(fs, jasperCompiledReportFileName, parameters);
return reportTask;
}
indeed it goes out and starts to create the pdf. I see the the pdf in
/var/folders/2d/23408oihsdvh08r23/T/Brief3234987239872398472.pdf
However, just when DownloadIsComplete's appendToResponse method is called I get
errors:

I can provide more but I have to start somewhere.
I don't know what else to says other than 'HELP'!!! i'm drowning.
