Bug in Flex Toolkit, fix included

Hi,
the latest flex toolkit contains a bug when doing a DescribeLayout Call and the editLayoutSection contains only a single section. DescribeLayout throws a null-pointer error in this case.
Since the source is available, I did a quick fix so the maintainer of the toolkit can add it to the respository.

Code:

nice, thanks!

After a second look I noticed that the next few lines of code handling the relatedList part contains the same bug. So if you apply the patch, this should be fixed too.

Cheers,

Hi Ron,

Did this fix ever get into the Toolkit?  I'm also getting an error for describeLayout when trying to get stage picklist values for a specific opportunity RecordType.  Here's the code:

Code:
    private function GetRTStages():void
    {                     
        apex.describeLayout("Opportunity", [RecordType],
              new AsyncResponder(GetRTStages_CB, genericFault));
    }

 And here's the error:

TypeError: Error #1009: Cannot access a property or method of a null object reference.
    at com.salesforce.results::DescribeLayout()[/home/jamesw/projects/mavericks/sdk/src/com/salesforce/results/DescribeLayout.as:54]
    at com.salesforce.results::DescribeLayoutResult()[/home/jamesw/projects/mavericks/sdk/src/com/salesforce/results/DescribeLayoutResult.as:71]
    at SalesForceResponder/result()[/home/jamesw/projects/mavericks/sdk/src/com/salesforce/Connection.as:1259]
...

Thanks,
Dean
