Draggable formpanels don't destroy properly

Question

I have a grid with records from a store using the modern material theme on ExtJS 7.2. I want to create multiple floating, draggable formpanels from this view, but when I drag the formpanel around, closing it leaves a blank white space where the formpanel was, obscuring the background. Here is the source for the formpanel.

onItemClick: function (grid,rowIndex,e) {
    var record = grid.getStore().getAt(rowIndex);
    var form = Ext.create({
        xtype: 'formpanel',
        id: `${record.id}_form_${record.get('blah')}`,
        title: `Invoice ${record.get('blah')}`,
        floating: true,
        closable: true,
        centered: true,
        draggable: true,
        shadow: true,
        width:300,
        height:window.innerHeight*0.8,
        scrollable: true,
        modal: null,
        items: [
            {
                xtype: 'textfield',
                name: 'Blah',
                label: 'Blah',
                value: record.get('blah'),
            },
            {
                xtype: 'toolbar',
                docked: 'bottom',
                items: [{
                    xtype: 'button',
                    text: 'Save',
                    ui: 'raised round',
                    iconCls: 'x-fa fa-save',
                    handler: function() {
                        var theform = this.up('formpanel').getFields();
                        record.set(
                            {
                                'blah': theform['Blah'].getValue(),
                            }
                        );
                        this.up('formpanel').destroy();
                    }
                },'->', {
                    xtype: 'button',
                    text: 'Cancel',
                    ui: 'raised round',
                    iconCls: 'x-fa fa-close',
                    handler: function() {
                        this.up('formpanel').destroy();
                    },
                }]
            }
        ]
    });
    Ext.Viewport.add(form);
}

Does anyone have experience with this problem? I have tried messing around with a custom Ext.drag.Source object, but with no success so far. When I try to close a formpanel that has been dragged, I get an error:

TypeError: Argument 1 of Node.replaceChild is not an object.

Any help would be appreciated.

there is not property called "floating" in the modern toolkit. Did you mean "floated"?
Instead of adding to Viewport better use show() method.

Something like this:

onItemClick: function (grid,rowIndex,e) {
    var record = grid.getStore().getAt(rowIndex);
    var form = Ext.create({
        xtype: 'formpanel',
        id: `${record.id}_form_${record.get('blah')}`,
        title: `Invoice ${record.get('blah')}`,
        floated: true, // It is not called "floating"
        closable: true,
        centered: true,
        draggable: true,
        shadow: true,
        width:300,
        height:window.innerHeight*0.8,
        scrollable: true,
        modal: null,
        items: [
            {
                xtype: 'textfield',
                name: 'Blah',
                label: 'Blah',
                value: record.get('blah'),
            },
            {
                xtype: 'toolbar',
                docked: 'bottom',
                items: [{
                    xtype: 'button',
                    text: 'Save',
                    ui: 'raised round',
                    iconCls: 'x-fa fa-save',
                    handler: function() {
                        var theform = this.up('formpanel').getFields();
                        record.set(
                            {
                                'blah': theform['Blah'].getValue(),
                            }
                        );
                        this.up('formpanel').destroy();
                    }
                },'->', {
                    xtype: 'button',
                    text: 'Cancel',
                    ui: 'raised round',
                    iconCls: 'x-fa fa-close',
                    handler: function() {
                        this.up('formpanel').destroy();
                    },
                }]
            }
        ]
    });
    form.show(); // Show instead of add to Viewport.
    //Ext.Viewport.add(form);
}

Thanks for the help! I figured it was something simple like that that I just wasn't thinking of. — Jude Quintero, Jun 05 '20 at 12:42
