Answer 1

In hopes that someone can give me some guidance, I've duplicated the issue on my apex.oracle.com workspace.
Workspace: NBPERP
Username: GUEST
Password: 12summer3
Application: 464. Report Demo
Page 1 - a drop down list with submit will show that a query, when run, will return values.
Shared Component/Report Layout: LAYOUT TESTER - a simple RTF with some unique text that mimics the table shown on page 1.
Shared Component/Report Query: TEST REPORT - the same query that is being executed on Page 1. If I click into the query and set the bind variable to "Indy" (no quotes) and then Apply Changes, I can download an XML file with the correct data. If I think click "Test Report", I get a "no data found" (unexpected condition #1). If I click back into the query and set the bind variable, click "Test Report", again, I get a "no data found" message (unexpected condition #2).
Any help/direction on this problem would be much appreciated.
