2011 rowColumnLayout

[mark-paper]

dear all,
it is always me. This time I am fighting with the rowColumnLayout to set up a simple GUI.

to make it simple try to load the following codein maya 2011 and maya 2009 (i dont know about 2010 since i dont have it)

//*/*/*/*/*/*/*/*/*/*/*/*/*/*/*/*/*/*/*/*/*

if (window -exists testWin)
    deleteUI testWin;

window
    -width 500
    -height 300
    -mnb 1
    -mxb 0
    -resizeToFitChildren 1
    testWin;

rowColumnLayout
    -nc 2
    -cw 1 200
    -cw 2 300
        mainParent_RCL;

    columnLayout
        -width 300
        -adjustableColumn 1
        -backgroundColor 0.02 0.3 0.34    
            left_container;

        button;button;button;button;

setParent mainParent_RCL;

    columnLayout
        -width 20
        -adjustableColumn 1
        -backgroundColor 0.1 0.5 0.63
            right_container;

        button;button;button;button;
        button;button;button;button;
        button;button;button;button;

showWindow testWin;

//*/*/*/*/*/*/*/*/*/*/*/*/*/*/*/*/*/*/*/*/*

• In MAYA 2009: It get me the result I want. THe two column layout contained in the rowColumnLayout are aligned on the top of the window

• in MAYA 2011: it alligns the two column layouts vertically in order to put the shorter/smaller one aligned vertically on the middle poin of the longer one.

My question is: What have I to do in order to obtain the same result I got in maya 2009 with the last maya version?
That means: how can align both on the top of the two column, generated via rowColumnLayout, the two "sub" columnLayout?

Thanks in advance for your kind help, I owe you one

Cheers
