Dispose operation executed prematurely when requested after reparenting

[cpetrov]

Problem description

When disposing a container right after its children have been moved to another container, those children will not be laid out.

It seems that the dispose operation is executed right away, before the children update is flushed.

From _removeChild(child): https://github.com/eclipsesource/tabris-js/blob/7bd6a864a0c600a0d360724ef902c94bf7fd1626/src/tabris/widgets/Composite.js#L152 From dispose(): https://github.com/eclipsesource/tabris-js/blob/7bd6a864a0c600a0d360724ef902c94bf7fd1626/src/tabris/NativeObject.js#L346

Environment

• Tabris.js version: 3.3

Code snippet

import { Composite, TextView, contentView } from 'tabris';

let container = <Composite stretch />;
let thing = <TextView center text='Hello world!' />;

contentView.append(
  container.append(
    thing
  )
);

setTimeout(() => {
  thing.detach();
  thing.appendTo(contentView);
  container.dispose(); // does not work
  // setTimeout(() => container.dispose()); // works
}, 2000);
