Bug Demos

Client-side error on expander button

We got client-side error on expandable/accordion content.

Uncaught TypeError: Cannot read property 'parentNode' of null
at init-components-browser.js:259
...

To re-produce the bug: Run the server and go to:

• http://localhost:8080/clickable-expander.
• or http://localhost:8080/clickable-expander-no-textual-display

However, if we remove the client-side behaviour (no component.js and click event handlers), the error is gone: http://localhost:8080/non-clickable-expander

Client-side error on dialog component

We got client-side error on clsoign and showing dialog component:

Component.js:542 Uncaught TypeError: Cannot read property 'nextSibling' of null
  at Component.___forEachNode (Component.js:542)
  at Component.___detach (Component.js:533)
...

To re-produce the bug: Run the server and go to:

• http://localhost:8080/bug-dialog-close.

However, if we simplified the dialog (simple text instead of nested component Textual Display), the error is gone (http://localhost:8080/bug-dialog-close-no-textual-display)
