Taken from the StackOverflow question 'Why does 'show' event on Kendo View fire twice?' https://stackoverflow.com/questions/56266538/why-does-show-event-on-kendo-view-fire-twice

If a Kendo View is rendered into a Layout (using layout.showIn()), the show event for the view fires twice. Interestingly, if the view is rendered directly into a DOM element (using view.render()) the event is only fired once, like it's supposed to.

The code is pretty well copied from the Kendo UI Dojo thingee. I wonder if can you run this :https://dojo.telerik.com/AkOwiMAZ/2

<div id="app"></div>
<script>
var foo = new kendo.View("<span>Foo</span>", { hide: function() { console.log("Foo is hidden now"); }, show: function() { console.log( "Foo is shown now"); }});

var layout = new kendo.Layout("<header>Header</header><section id='content'></section><footer></footer>");

// Creating the layout, and using the showIn method to render the view
// is where I'm having the issue (2 'show' events fire)
layout.render($("#app"));
layout.showIn("#content", foo);
//
// But this way works fine (rendering directly to a DOM element) (just // one 'show' event fires)
//foo.render('#app');
</script>

Using the MobileView AngularJS directive throws an error upon initialization. This is a regression from 2019 R2 release.

Reproduction of the problem

https://dojo.telerik.com/EpobaCid

1. Navigate to: https://dojo.telerik.com/AJoVUwen/2
2. Click setOptions button multiple times.
3. Sort some column

Result: The old events handlers are not cleared(see the console).

When a bullet list with a nested table is created in Word, and then copied into the Editor, a "Cannot read property 'cells' of undefined" error is being thrown. The issue can be reproduced only when the msConvertLists option is set.

Reproduction of the problem

1. Open https://demos.telerik.com/kendo-ui/editor/paste-cleanup

2. Paste content from editor-test.docx.

Bug report

Unable to resize a column inside a table inserted in Editor

This is a regression represented after Kendo UI 2019.2.619

Reproduction of the problem

1. Open this Dojo and run it
2. Add a table(no matter of its size)
3. Try to resize a column, not the whole table. No matter of the direction you resize the column its board is moving to the left
4. When you release the mouse button the column is resized in a totally different way than the resize indicator showed

Current behavior

Please check this video for more details

Expected/desired behavior

The columns inside a table should be resizable.

Environment

• Kendo UI version: 2019.2.619
• jQuery version: x.y
• Browser: [all]

Bug report

Defining a custom namespace with Kendo.ns stops the displaying of all submenus in the Menu component.

This is a regression represented in R2 2019

Reproduction of the problem

1. Open this Dojo and run it.
2. The Menu component is being rendered
3. Move the mouse cursor over the Menu.
4. A thin grey line appears under each section of the Menu. No submenus are being displayed

Expected/desired behavior

The Menu component should work properly even when a custom Kendo namespace is being defined. To see the expected behavior put a comment on the following line:
kendo.ns = "kendo-";

Environment

• Kendo UI version: 2019.2.619

Bug report

When Kendo UI is integrated within an Angular 8 App, WebPack incorrectly bundles ripple.js util, thus leading to an error when the script is loaded.

Current behavior

A "cannot read property 'kendo' of undefined" error is being thrown after bundling.

Expected/desired behavior

No error should be thrown when bundling the Kendo script.

Environment

• Kendo UI version: 2019.2.619

Bug report

Once the content area is blurred it can be focused only by clicking its upper part.

Regression introduced in R2 2019 SP1. Reproducible only in Chrome.

Reproduction of the problem

Demos. Screencast.

1. Clear the Editor's content.
2. Blur the widget and try to focus the content area by clicking in its bottom or mid section.

Current behavior

Content is not focused.

Expected/desired behavior

Content is focused.

HtmlPage1.zip

Reproduction of the problem

1. Run the attached page in the browser.
2. Take a 20 sec long heap snapshot. During these 20 sec click the "change" button to make changes to a specific node's data in the observable.

Current behavior

There are multiple detached span elements: screenshot
Memory consumption increases with every change: screenshot

We recently upgrade Kendo UI from version v2019.1.220 to 2019.2.619 and our user base is freaking out because they can't select the text on web pages that use the splitter. 

https://dojo.telerik.com/IbARuWod

When the Kendo UI Treelist is horizontally scrollable and a filter is applied which returns no items, the scrollbar disappears. Therefore, if the column is one of the hidden ones, it would be impossible to navigate to it in order to clear the filter. 

A Dojo sample for the reproduction of the issue:

https://dojo.telerik.com/IQuHuNej

dojo: http://dojo.telerik.com/UMuRaBax/3

Steps to reproduce:

1. Run the dojo, let the comobox list load and let it select the default item ('Oulu' in this case).

2. start typing 'Madrid' in the input field of the combobox.

3. press Tab key and observe behavior.

Bug report

The Toolbar's overflowAnchor property is missing from the Kendo typing definitions. It is also not available in the Toolbar's API.

Reproduction of the problem

Current behavior

Typing definitions for overflowAnchor are missing.

Expected/desired behavior

The overflowAnchor property should be available for the Toolbar and added to the API as well.

Environment

• Kendo UI version: 2019.2.619

• Browser: [all ]

Working dojo example to reproduce: https://dojo.telerik.com/aMEKuzex/2

If you set the contents of the combobox using the text() method, pressing the "X" inside the ComboBox will not fire a change event.

If you set the contents of the box using the value() method, or through the UI itself, clearing it afterwards does fire the change event, which is the expected behaviour. 

1. Create a grid with two editable columns.
2. Define validation rules for both columns. Keep one column as required.
3. Edit the row. Set the required column value using model.set method.'

It fails because before setting the value it performs validation. If validation was successful then it will set the value on model.

Since the desired field has no value and validation rule will fail on that.

It should accept the value and then perform validation. If validation fails with new value then it might discard the changes.

$("#grid").kendoGrid({
  dataSource: {
    batch: true,
    transport: {
      read: function(e){
        e.success([1,2,3,4,5,6,7,8,9].map(function(i){return {id: i, title: "test" + i}}));
      }
    },
    schema: {
      model: {
        id: "id",
        fields: {
          id: {defaultValue: "-1"},
          title: {
            validation: {
              required: true
            }
          }
        }
      }
    }
  },
  columns: [
    {field: "title", title: "Title", filterable: {field: "title.a"}},
    {command: ["edit", {name: "destroy"}]}
  ],
  editable: {mode: "inline"},
  filterable: true,
  toolbar: [{name: "create"}]
});
 
var grid = $("#grid").getKendoGrid();
var model = grid.dataItems()[0];
grid.editRow(model);
model.set('title', '');
model.set('title', 'test 1111'); // it will fail

Bug report

When exporting a diagram as a PDF, hidden shapes still visible. 

Reproduction of the problem

1. Run this dojo - https://dojo.telerik.com/oRUPUHOb/4
2. Click on "Mask" button
3. Click on "Save as PDF"
4. Open the exported PDF file

The shape State 1 must not be present on the exported PDF

When the grid is configured for InCell editing and frozen columns, it is expected the first editable cell to be opened for editing when a new record is added. 

However, when there is not an editable cell in the locked columns, it would not search in the main content. Here is an example:

https://dojo.telerik.com/ucEraQOW

A temporary workaround would be to override the editModel function and check in the second table as well:

When using IE 11 and using Ctrl+X to cut, this only works the first time. All subsequent attempts to use cut produce the following dialog:

Bug report

Reproduction of the problem

Dojo example.

Current behavior

The mobile material theme does not apply specific styles to a button that has the "km-primary" class. Compare to the Nova mobile theme, which does have specific rules that use ".km-primary" selector.

Expected/desired behavior

CSS rules that use the ".km-primary" selector should be added to the theme.
