Disabling Tooltip Indicator for a Label field

Hi,

I am using Adobe Flash Builder 4.7 for an Flex Air Application. In UI part mxml file with .as Renderer code.

I am using an indicator, say *, in a label field for tooltips display.

<s:Label  text="Project Name"  toolTip="Enter project name"  /> <s:Label  id="TooltipIndicator"  text="*" />

And it is dispalyed as

Project Name*

indicating there is a tooltip for this Label.

Now the problem is, I want to hide or  make invisible this indicator when I disable TooltipManager. I want this to happen globally for all the indicator labels in my application.

Thank you
