    Default Answered: Hiding of all hideable columns not allowed?

    I noticed that a user cannot hide all columns in a gridpanel. It seems that the grid must at least display one column. I can imagine this is a nice feature, but it doesn't work quite as I expected when dealing with both hideable and non-hideable columns. It seems that the rule is that at least one hideable column is required to display, even if there is a non-hideable column in the grid.

    It doesn't make sense to me to not allow hiding of all hideable columns when at least one non-hideable column is displayed. Is this behaviour configurable?

    I created a demo based on the Stateful Array Grid Example showing the problem:

  2. A simple hack is to allow all columns to be hidden unconditionally (in my application I don't bother about checking whether hideable columns exist, because I know they do...)

        updateMenuDisabledState: function()
            var me = this,
            result = me.getLeafMenuItems(),
            total = result.checkedCount,
            items = result.items,
            len = items.length,
            i = 0,
            rootItem = me.getMenu().child('#columnItem');
            //if (total <= 1)
            if (total <= 0) /* Allow all columns to be hidden unconditionally */
                me.disableMenuItems(rootItem, Ext.ComponentQuery.query('[checked=true]', items)[0]);
                for (; i < len; ++i)
                    me.setMenuItemState(total, rootItem, items[i]);
