[jira] [Created] (PIVOT-994) BXMLExplorer is getting a null display for a visible owner window.

JIRA jira@apache.org
Roger Whitcomb created PIVOT-994:

             Summary: BXMLExplorer is getting a null display for a visible owner window.
                 Key: PIVOT-994
                 URL: https://issues.apache.org/jira/browse/PIVOT-994
             Project: Pivot
          Issue Type: Bug
          Components: core-beans
    Affects Versions: 2.0.4, 2.1
         Environment: All
            Reporter: Roger Whitcomb
            Assignee: Roger Whitcomb
            Priority: Minor
             Fix For: 2.1, 2.0.5

Run the BXML Explorer Tutorial application.  Open up the "org/apache/pivot/tests/alert_prompt_test.bxml" file and try to bring up any of the alerts or prompts.  There will be an IllegalArgumentException that "display is null."

The stack trace (for 2.0.x) shows this:
java.lang.IllegalArgumentException: display is null.

This sequence shows that "owner.getDisplay()" is returning null at Alert.open() time, even though the owner window is clearly visible at the time.

This could possibly be due to Nashorn scripting issues with Java 8, since the "window" variable would be set in the JS namespace, but this doesn't really explain why the "display" value is null, and not the "window" value itself.
