You'll have to call onchange on select tag

Just you are missing the props, you try to call courses from Course component direct, so that when you add the props before, all is work fine..

To get your "stack of CellViews" to grow from the bottom, you need to embed that stackView in another "container" view.

• Add the stackView as a subview of the stackContainer view
• constrain the stackView Leading / Trailing / Bottom all equal to Zero
• constrain the stackView Top greater-than-or-equal to Zero... that will keep the stackView at the bottom, but will force the stackContainer to grow when it gets tall enough
• Add the stackContainer view as a subview to the scrollView
• constrain all 4 sides of that stackContainer view to the scrollView's .contentLayoutGuide to control the "scrollable area."
• constrain the stackContainer's width to the scrollView's .frameLayoutGuide width

The "tricky" part is this: we also constrain the stackContainer view's height equal to the scrollView's .frameLayoutGuide height, but we set the priority of that constraint to less-than-required -- such as .defaultHigh. This will keep the stackContainer view equal to the height of the scroll view's frame, until the stack view gets tall enough to make it grow.

Here's how it looks when running:

It's because of this.

Here's what I use in a test helpers file:

Specify what date you want like so (Year, Month, Day):

So, as I noted before in my notes, the problem that I was have was caused by how Lucid's query builder handles the paginate function, so I was forced to "roll my own". Here's what I came up with:

That's simple , those method come with every widget that extend or inherit the WidgetBase dojo class ,

Dojo widget passes thorough different life cycle method , among those we find the last two method postCreate and 'startup' ,

if you want postCreate comes just before startup in lifecycle , note that postCreate just finished to create your widget but may not yet attached to dom , also its child widget not mounted ,

On the other hand the startup come after widget rendrer with it's child widgets and mounted to dom.

so if you have any layout calculation , or dom related function , you may not use postCreate for this , and should use staartup to ensure widget has finished mounting to DOM

And against my expectations it rerenders each time when parent component rerenders after Increase button is pressed.

Did i misunderstood something?

That's the default behavior in react: when a component renders, all of its children render too. If you want the component to compare its old and new props and skip rendering if they didn't change, you need to add React.memo to the child:

You are not doing what the zlib documentation says to do, which you yourself highlighted in the question. Use dup().
