dynamically initializing a child component at run time

In a current Flex project, i have an issue where a certain child component must be initialized and ready when the user clicks a button. the button is a mouseClick Event.

//mouseClick Event

protected function tableSearch_searchClickHandler(event:MouseEvent):void
        {

            parentXml = event.xmlNode;
            if(classifierInfo)
            classifierInfo.variables = parentXml;
            else //initialize it dynamically..but how?
            {};
}

in the function the component (classifierInfo) is checked to see if it is initialized and ready== that is, it is not null. then the variables property is populated with the parentXm开发者_运维问答l value else, if it is not ready, [i want to initialize it dynamically] but do not know how.

does any one know how i could fill up the else statement such that the classifierInfo component is initialized dynamically? Is this even possible?

you have to try to initialize the object and add it to the correct parent UI Object if it is a visual component.

classifierInfo = new WhateverClass();
classifierInfo.somePropertySet
...
yourUIComponent.addElement(classifierInfo);

Is it that what you are trying to do?
