Hello,I am working on some modifications to the BA Report Widget to add the ability for my users to access the Census 2010 Profile Report in addition to the other included reports for our subscription. Short Problem Description:The code works with the USA dataset but the report request errors out when referencing the USACensus2010dataset.Details: When the code is referencing the "USA" dataset, it all works perfectly. The dropdown populates with the report names returned from the GetReportTemplates task, I can draw my geography, and when I click run report - I get my report.When I change the activeDatasetID to reference the USACensus2010, it does not work perfectly. The dropdown populates correctly with the single Census 2010 profile report returned from the GetReportTemplates task, I can draw my geography, but when I click run report - I get an error rather than a report.Here is the first function to populate the drop down list of report titles. This runs fine and is used to populate the dropdown list:private function getReportTemplatesTask() : void
{
cursorManager.setBusyCursor();
lblGuide.text = "Task is executing. Please wait.";
var getReportTemplatesTask : GetReportTemplatesTask = new GetReportTemplatesTask(_baClient);
//Added the activeDatasetID line to be able to change to the USACensus2010 dataset
getReportTemplatesTask.activeDatasetID = "USACensus2010"
//getReportTemplatesTask.activeDatasetID = "USA"
getReportTemplatesTask.execute(new mx.rpc.Responder(reportTemplatesResultHandler, reportTemplatesFaultHandler));
}
NEXT STEPS:I select the name of the only report from the drop down list populated by the code aboveDraw my polygon on the mapClick Run Report - it chugs for a bit and then errors out with a "can't reference Null object" error From what I can tell, the event object that the resultHandler receives from the ExecuteReportTask function is empty but I do not understand why it is empty. Is there documentation or an example of the difference in the request structure for the USA vs the USACensus2010 reports? The code that launches from the "Run Report" is shown below. It works great with the USA dataset but not the USACensus2010 dataset.
private function executeReportTask(polygon : Polygon) : void
{
if (polygon)
{
cursorManager.setBusyCursor();
lblGuide.text = "Task is executing. Please wait.";

}
I just don't know why and as of yet have not found much documentation on accessing this report via the BAO API. Thanks for reading this far and any assistance would be much appreciated!!!Sincerely,AmyACOGGreenville, SC
