Retrieve Error Message in Keyword Test Try...Catch Block

I want a test harness like this:



function runTest(testName)

{

    var test = KeywordTests[testName];

    Pretest_Cleanup.discardChanges();

    var docReady = Pretest_Cleanup.waitDocumentReady(30000);

    if(docReady)

    {

        Pretest_Cleanup.removeAllSectionsManually();

        Pretest_Cleanup.addNewSection();

        try

        {

          test.Run();

        }

        catch(exception)

        {

          KeywordTest.handleException(exception);

        }

    }

    

    KeywordTest.endKeywordTest(test, docReady);

    KeywordTest.logTestResult(test);

}



"test" is a keyword test obtained from the KeywordTests object.  KeywordTest is a class that has functions useful for manipulating keyword test results and the test itself.



An example of an error I would want to catch and handle would be this:

"Unable to activate the disabled control."

Sys.Process("IEXPLORE").Page("https://wf-quality-staging-hrd.appspot.com/editor").Panel("flashContainerDiv").Object("WebFilings").WFDialog("File Manager").Button("btnOpen")



I want to handle all errors manually, but the above script block does not catch errors related to object manipulation like the example.  I tried wrapping the entire keyword test in a try...catch block, and that was what brought about the question of retrieving the error message in the first place.  Here's a screenshot: http://screencast.com/t/a0SrRDyccPD
