Question

What to do to hide Office manager: if {manager} is empty?

<mx:Text id="lblManager" text="Office manager: {manager}" width="220" height="20"/>

Answer 1

Try this. You may also test if "manager" is null:

<mx:Text id="lblManager" visible="{manager.length > 0}" text="Office manager: {manager}" width="220" height="20"/>
