> There is a major problem exists with dynamic or delayed child creation policy
> in FlexJS MDL implementation.
> MDL components are very much popular for their finer looks and many of their
> trendy animations etc. These animations etc. works good when you declare a
> child/component statically; that means the child/component was always there.
> In a real world application we can't declare all the available components at
> once. But these animations etc. fails badly when you adds a child/component
> at run-time, by some button click or by any other means.
> A statically declared child/component I refer as this:
> {code}
> <mdl:GridCell column="1" percentWidth="100">
> <local:TextFields percentWidth="100"/> <!-- An external component -->
> </mdl:GridCell>
> {code}
> A dynamically added child/component I refer as:
> {code}
> protected function onButtonClickEvent(event:MouseEvent):void
> {
> var externalComponent:TextFields = new TextFields;
> externalComponent.percentWidth = 100;
> gdCell.addElement(externalComponent);
> }
> ...
> <mdl:GridCell id="gdCell" column="1" percentWidth="100"/>
> {code}
> *Problem:* When you add any component by above dynamic way, the component
> lost all of it's animation, dynamism etc. Some components even became
> completely useless, i.e. Toast, Snackbar, expanding search field etc.
> I'm attaching herewith one demo project to demonstrate the problem I
> mentioned, which consists of two parts - 1. Half of the application displayed
> a form type of component added statically and having many text fields and
> they supposed to work properly and their animations when ran. 2. The
> application holds a button named "Click to add External components" upon
> clicking which adds the *_Same_* component from part#1 to fill the rest of
> the application area but dynamically. This part of the application's fields
> never works properly or their animations.
> Please, check.
