VS2010 Eliminate Group Tree Level

Question

I need to have a variable number of levels in the group tree in VS2010, a technique I have used in CR for VS2005. I also saw this resolved for someone using VS2008 on thread 8244145 using the same method that I used in 2005. If, at the most detailed level, I group on a formula that I have return a zero length string, that level still shows up in the tree and crashes the program if the user tries to drill down that far.
Group 1 formula
select {?level}
    case 1 : {XXX.AGENCY_CD}
    case 2 : {XXX.REGION_CD}
    case 3 : {XXX.ORG_CD}
default: ""
Group 2 formula
select {?level}
    case 1 : {XXX.REGION_CD}
    case 2 : {XXX.ORG_CD}
default: ""
Group 3 formula
select {?level}
    case 1 : {XXX.ORG_CD}
    default: ""

I set the grouping level to 3 (out of 1,2,3,4). If the level is 4, the tree makes no sense, so I hide it.
If I run the program from the IDE:
When I try to drill down in the GroupTree to the level that should not exist, Visual Studio breaks n allInOne.js with the error "Microsoft JScript runtime error: 'txtTooltipLyr' is null or not an object".
If I view it in the Main Report Preview in the IDE:
The 2 levels of nodes that should be eliminated are visible, but they do not do anything. The have no text and expanding the lowest level of the tree does nothing.
If I deploy the web page and run it without using the IDE:
The 2 levels of nodes that should be eliminated are visible, but they do not do anything. The have no text and expanding the lowest level of the tree does nothing, except that on the browser status bar there is an 'Error on page.' message.
I have never exported to RPT format. I just tried it and I had to open it with visual studio. It acts just like Main Report Preview described above.
DebugDiag does not show anything, I am guessing because the IDE is catching the error and nothing is really crashing.
