I am building a master - detail interface where Master is a dataGrid
and detail is a form.
...
<mx:FormItem width="110" direction="horizontal" label="Badge"
required="true">
<mx:TextInput id="badgeid" focusOut="formatBadge(badgeid)"
text="{templist.selectedIndex==-1 ? templist.dataProvider
[0].bedge_id : templist.dataProvider
[templist.selectedIndex].bedge_id}"
width="50" restrict="0-9" maxChars="5"/>
</mx:FormItem>
...
I am getting an error at:
text="{templist.selectedIndex==-1 ? templist.dataProvider
[0].bedge_id : templist.dataProvider
[templist.selectedIndex].bedge_id}"
The error:
Error: Unknown Property: '-1'.

Please help. Thanks
