You could try changing .visible and .includeInLayout
instead of adding/removing.
The best practice for resolving multiple properties
is to use the invalidatePropertie s/commitProperti es technique.

Not quite. I have items 0
through 5 I want them to be displayed in that order but if 4 is not displayed
then I get an out of bounds error when I addChild At 5. It may happen when 2 is
drawn even if 0 and 1 are going to be drawn but since I have no control over
order it evaluates the variables in the MXML invocation that will generate an
error also
i.e.
<reportComps: OrderBy id="userOrderBy"
showAssociate= "true" showArrival= "true"
showPDeparture= "true" showHost="true" />

The order of items in HBox/VBox is their childIndex order.
addChildAt(myButton , 0) should put it first.

When
showAssociate is set to true the button shows up, but I want it
always to show up first.
Here's my code:

this.addChild( myButton) ;

this.removeChild( this.getChildByN ame("associateRB "));
