Hey Gordon. Thanks for the answer. I tried your suggestion, but it still won't work.
I show once again what the problem is. I'm a novice, please keep this in mind ;-) This one works but it's case-sensitive. (The function liveSearch is unnecessary in this case. I know.): ---------------------------------------------------------------------- public function liveSearch(searchString:String):String { return searchString } <mx:TextInput id="searchStringInput"/> <mx:DataGrid id="dataGrid" dataProvider="{externalXML.customer.(name1.match(liveSearch(searchStringInput.text)))}" > ---------------------------------------------------------------------- If I add RegExs the troubles begin. I have a label to show what's the RegExs output and it's excatly what it should be. If the string is empty it works just fine. If I start typing it shows nothing. ---------------------------------------------------------------------- public function liveSearch(searchString:String):String { if(searchString == '') { return '' } else { var regExSearchString:RegExp = new RegExp(searchString, 'i'); var searchTerm:String = regExSearchString.toString(); return searchTerm } } <mx:TextInput id="searchStringInput"/> <mx:DataGrid id="dataGrid" dataProvider="{externalXML.customer.(name1.match(liveSearch(searchStringInput.text)))}" > ---------------------------------------------------------------------- I also tried a static variable but this one works neither. So, always when I trie to add RegExs over variables it causes problems. ---------------------------------------------------------------------- public var test:RegExp = new RegExp('Stich',i); public var test1:String = test.toString(); <mx:DataGrid id="dataGrid" dataProvider="{externalXML.customer.(name1.match(test1))}" > ---------------------------------------------------------------------- Does anybody know what the problem could be?
