You could try changing .visible and .includeInLayout instead of adding/removing.
The best practice for resolving multiple properties is to use the invalidateProperties/commitProperties technique. ________________________________ From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Sean Sell Sent: Tuesday, June 05, 2007 11:13 AM To: flexcoders@yahoogroups.com Subject: Re: [flexcoders] Re: Selecting which Child Components to add at runtime 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"/> ----- Original Message ---- From: Alex Harui <[EMAIL PROTECTED]> To: flexcoders@yahoogroups.com Sent: Tuesday, June 5, 2007 1:20:41 PM Subject: RE: [flexcoders] Re: Selecting which Child Components to add at runtime The order of items in HBox/VBox is their childIndex order. addChildAt(myButton , 0) should put it first. ________________________________ From: [EMAIL PROTECTED] ups.com [mailto:flexcoders@ yahoogroups. com] On Behalf Of rough68fish Sent: Tuesday, June 05, 2007 10:05 AM To: [EMAIL PROTECTED] ups.com Subject: [flexcoders] Re: Selecting which Child Components to add at runtime When showAssociate is set to true the button shows up, but I want it always to show up first.
