Why can I pass a string, but not a date?

[Ian Skinner]

I have this custom component that at the moment just repeats the passed
in value. It works if I pass in a string, but if I pass the date I
actually want it does not work. I can not figure out why.

dayFormat2 custom component.
<mx:Script>
<![CDATA[
//Define public variables
public var dayData:String;
]]>
</mx:Script>

<mx:DateFormatter id="dayNum" formatString="DD" />
<mx:Label text="{dayData}" />

-----------------------

This Works.
<ns1:dayFormat2 dayData="George" />

This Does not work.
<ns1:dayFormat2 dayData="{DayNum.format(dayCells.currentItem.date) }" />

And neither does this. Of course for this version I change the dayData
type to date in the custom component.
<ns1:dayFormat2 dayData="{dayCells.currentItem.date}" />

Just to make sure that the date exists as I expect. If I replace the
dayFormat2 custome comment with a label, I get the dates just fine.
<mx:Label text="{DayNum.format(dayCells.currentItem.date)}" />

Well I cant tell you why it works with "george" as the data, but I know that a
date that is formated is not a date anymore, its just a string.

I had this problem a little while back where I was trying to store a formated
string as an attribute of my object but it never stored correctly. After
asking around I found I had to write a function that could take my formated
date string and construct a real date object to be used later.

Hope that helps put you on the right track.

I have tried it both ways, to pass the date itself and a formated string
of the date, since the hard coded string worked. Neither provides any
results. I just get a blank screen. No error, just a blank screen.

add the bindable meta in your custom component...seems like that would
be needed.

//Define public variables
[Bindable]
public var dayData:String;
