  • Can't select the first node in a TreeGrid

    Hello,

    I'm seeing a problem in the latest nightly where I can't select the first node in a tree with checkboxes. You can recreate it by compiling this showcase page with the nightly. I believe the problem is this TreeGridBody method. When this.selectRecord(_2, _1) is called, _1 is the index of the row. Further down the stack, that arg gets reused as a boolean, and if it's false (which happens if the index is 0), the method returns early and the row isn't selected. The code that the showcase is currently using calls this.selectRecord(_2), which works fine.

    Code:
         
    isc.A.mouseDown = function isc_TreeGridBody_mouseDown() {
            var _1 = this.getEventRow()
              , _2 = _1 < 0 ? null : this.grid.data.get(_1);
            if (_2 != null) {
                if (this.grid.clickInOpenArea(_2)) {
                    return isc.EH.STOP_BUBBLING
                } else if (this.grid.clickInCheckboxArea(_2) && this.canSelectRecord(_2)) {
                    var _3 = this.grid.selectionType;
                    if (_3 == isc.Selection.SINGLE) {
                        this.deselectAllRecords();
                        this.selectRecord(_2)
                    } else if (_3 == isc.Selection.SIMPLE || _3 == isc.Selection.MULTIPLE) {
                        if (this.selectionManager.isSelected(_2, _1)) {
                            this.deselectRecord(_2, _1)
                        } else {
                            this.selectRecord(_2, _1)
                        }
                    }
                    return isc.EH.STOP_BUBBLING
                }
            }
            return this.Super("mouseDown", arguments)
        }
    
    //Further down the stack, see comment below.
    isc.A.selectList = function isc_Selection_selectList(_1, _2, _3, _4, _5) {
            if (_2 == null)
                _2 = true;

    Thanks for pointing this out. We believe only SGWT 12.1d/SC 12.1d were affected. A fix has been committed that should be in the nightly builds dated 2019-02-02.
