Search results to grid.

[AmandaHutsel]

I'm trying to search a feature layer and have the results show on a map and also in a grid.  Both are working, the bug is that when you hit the "Find" button once the results show on the map and then you have to hit it a second time for the results to show in the grid.  Any ideas on solving this would be helpful.  Here is my search function code:

var featureset:FeatureSet;
  
private function doHSearch():void
{
var str:String="Street_Address like '%" + addressText.text+"%'";
   
if(statusText.selectedIndex != -1)
{
  str=str+ " and ConStatus = '" + String(statusText.selectedItem) + "'";
}
   
if (refText.text != "")
{
  str=str+" and ReferenceNo = "+ refText.text
}
   
if (apnText.text != "")
{
  str=str+ " and AssessorParcelNo = " + apnText.text
}
   
historic.definitionExpression=str;
   
featureset = new FeatureSet(ArrayCollection(historic.graphicProvider).toArray());
ResultsGrid.dataProvider = featureset.attributes; 
}

Amanda,

That's strange functionality.  Are you sure it's just not taking a while for the data to load into the grid?  Sometimes it takes a while for large feature sets to show up into the datagrid.  I would try waiting a little while before hitting the button again.  Otherwise, that's weird.  A second button click should be the same command as the first...

I've waited 5 minutes and nothing happens until I hit the find button again.

What's the code behind the Find button (and it helps if you put the code inside the Code tags)?

[AmandaHutsel]

The code for the find button is this:

<s:Button click="doHSearch()" label="FIND"/>

I'm not really sure what you mean by "it helps if you put the code inside the Code tags".

Amanda,
what is your debugger shows?

historic is smthing like FeatureLayer? listen it's update events. When the layer has finished updating its content - get graphicProvider and "play" with features.

...
historic.addEventListener(LayerEvent.UPDATE_END, onHistoricUpdateEnd);
...
protected function onHistoricUpdateEnd(event:LayerEvent):void
{
    if (event.updateSuccess)
    { 
        trace("layer 'historic' update success");
        var historicGraphicProvider:ArrayCollection = historic.graphicProvider as ArrayCollection;
        if (historicGraphicProvider && historicGraphicProvider.length > 0)
        {
            trace(historicGraphicProvider.length + " features found");
            featureset = new FeatureSet(historicGraphicProvider.toArray());
            ...
        }
    }
    else
    {
        trace("layer 'historic' update not success");
    }
}
...

here is working sample - using defenitionExpression
here is working sample with sources - using query (all conditions you can put as where clause string "address like ...")
