SectionStack section move bug

[jiri.ov]

Hi all,

I probably found bug in SectionStack implementation. I am able to reproduce it on your current examples: http://www.smartclient.com/#resizeSections with modified code:

isc.defineClass("HelpCanvas", "Canvas").addProperties({
    autoDraw: false,
    padding: 10,
    overflow:"auto",
    contents: "<b>Severity 1</b> - Critical problem<br>System is unavailable in production or " +
              "is corrupting data, and the error severely impacts the user's operations." +
              "<br><br><b>Severity 2</b> - Major problem<br>An important function of the system " +
              "is not available in production, and the user's operations are restricted." +
              "<br><br><b>Severity 3</b> - Minor problem<br>Inability to use a function of the " +
              "system occurs, but it does not seriously affect the user's operations."

});

isc.SectionStack.create({
    ID: "sectionStack",
    visibilityMode: "multiple",
    width: 300, height: 350,
    border:"1px solid blue",
    sections: [
        {title: "Blue Pawn", expanded: true,  canCollapse: true, items: [
              isc.HelpCanvas.create({ ID:"help0", autoDraw:false })
        ]},
        {title: "Help 1", expanded: true, canCollapse: true, items: [ 
            isc.HelpCanvas.create({ ID:"help1", autoDraw:false })
        ]},
        {title: "Help 2", expanded: true, canCollapse: true, items: [ 
            isc.HelpCanvas.create({ ID:"help2", autoDraw:false })
        ]}
    ]
});

isc.IButton.create({
    left: 325,
    width: 150,
    title: "Resize Help 1",
    click: "help1.setHeight(200)"
});

1) Close to section "Help 1"
2) Try to move section "Help 2" (by dragging section header)
=>BUG: JavaScript error with this stack trace:

I tested it on version: v9.0p_2014-01-01/LGPL Development Only (built 2014-01-01), FF ESR 24.4

Thanks for the clear report. This is fixed for tomorrow's builds for all affected branches.
