Have found the error:
Here's the working code:
----------------------------------------------------------------------
public function liveSearch(searchString:String):RegExp {
var regExSearchString:RegExp = new RegExp(searchString, 'i');
return regExSearchString;
}
<mx:TextInput id="searchStringInput"/>
<mx:DataGrid id="dataGrid"
dataProvider="{externalXML.customer.(name1.match(liveSearch(searchStringInput.text)))}"
...
----------------------------------------------------------------------
Problem was that I have to return a :RegExp not a :String for the live
search function.
Stupid, Stupid me...
What i now have is very cool: a real LiveSearch feature with just a
few lines of code.
