If I understand you code right, as documented

Do not modify objects or values inside the model manually; always use the provided API to change data in the model, or use two-way binding (see Two-way Binding section below).

What you are doing is not officially supported. Use only API methods.

The is a runtime artifact that is not part of the DOM but serves only the purpose of wrapping multiple XML root nodes in *.fragment.xml documents. I.e.:

^{From the topic "Fragments with Multiple Root Nodes"}

A view in UI5 is never destroyed once it is displayed (and controller's onInit is also called only once).

If you take a look at the sample app for step 5 of the routing tutorial, you see a small app, that opens a second view when clicking a button.

In the UI5 diagnostics (Ctrl+Shift+Left Alt+S), you can see the control tree for both views:

Also, when you deploy the UI5 application, the tooling will generate a Component-preload.js file that contains all views and JS files in one file.

So no, there is no garbage collector cleaning anything up for you.

[...] multiple controls created from an aggregation binding

With this.byId("myReportCardContent"), you're accessing the template control rather than the actual rendered ones. A template in aggregation binding is usually a static control (i.e. without propagated models and contexts) that the ManagedObject will clone for each data object. After cloning, the parent models and contexts are propagated to those clones, and not to the internal template control.

So if you add the popover to the dependent aggregation of the template (oRootHBox), there is no context to propagate. The binding paths in the fragment definition stay unresolved.

How the issue can be circumvented is up to you. There are many approaches to show something on mouseover. Just avoid manipulating the template after rendering.

You can control the content size with the properties contentWidth and contentHeight.

Update after the comment:

but more interesting is the reason why does the showing of extra [content] leads to change the dialogue window size?

That's probably the native behavior of Blink (Chromium's layout engine). If an additional HTMLElement needs to be rendered and the Dialog's

According to this comment, other browsers behave differently. So the Dialog tries to "fix" it in that case.

So here is what I have to do to close the handle. I have added the following lines after opening the MSI file:

I found a simple way to create surface view and use a canvas to draw on. The problem with most info on the internet is the fact, people are giving unecessary code...they're writing too much or including things that don't need to be included in order to show someone the simplest example form.

Here is the simplest example form of creating a surface and using canvas to draw (android 30).

the problem is the following two lines of code.

Refactoring that is pretty easy, all you need to do in addition is flagging the method you're calling it from as async, which is really the only change you need to make.

The biggest potential issue you'll have is browser support, if you don't run your codebase through a tool like Babel. The biggest hurdle is IE 11, which many enterprise customers still use.
