Passing Parameter to Flex Viewer

Amber,

Great news. The funny thing is that I am sitting here writing my Developer Summit powerpoints for my presentation and I have a bullet in one that says don't forget to set that to false if you are not using ArcGIS Server 10...

Thank you Mark, this worked great.
If it wasn't for this forum, and contributors like Robert, Mark, and many others, my Flex application would be rather plain and my aggravation level would be much higher.
Thanks,
Bill

Thanks Marc!!! This is a really big help to me (and it looks like others too!!).

I might be asking too much here, but I am wondering if it is possible to have an info popup come up on the queried polygon feature in the url?

JeffHarmon

Great question Steve. Also, any insight on changing the zoom level? Thanks this has been very helpful.

SteveWhitehead__GISP

Jeff, I added the map.scale within the maploadcomplete. It zooms to the set scale.

//hideProgress(); // Hide the progress bar
map.extent = unionExtent;
map.scale = 5000; // Zoom to queried polygon

JeffHarmon

Thanks Steve. That is exactly what I was looking for.

I am trying to use Robert's solution in the following thread:
http://forums.esri.com/Thread.asp?c=...04#msgid923901

but am having trouble with something that seems very basic....

I cannot find the "SiteContainer.xmxl"

I searched my solution in FB4 but only found 2 mentions of it...one in the code I just pasted from the thread and the other in a comment in the AppEvent.as

Do I need to create one?

Molly,

If you are using Flex Viewer 2.x then there is no longer a SiteContainer, it is now called ViewerContainer.

aha!, so I was not going crazy!
Thanks Robert.
so, I need to co throught the code and change where it says SiteContainer to ViewerContainer and put the init() code into the ViewerContainer instead of the SiteContainer?

that is what I will try...

So that solution isn't for 2.x. I have run into many other errors, such as creating an AppEvent. You are passing 4 parameters, but the 2.x constructor is looking for <=3.

I don't know what other error I am going to run into...and not sure how to fix this one mentioned...not sure which params we need to pass. seems very different from older version of the viewer.

Well, I just went with the string and then null, null, to get passed the error.

Now the errors with BaseWidget and IBaseWidget
in the TimerComplete function:
This section:

 if (bWidget){
 var bWidg:BaseWidget = bWidget.getInstance();
 var vSW:SearchWidget = bWidg as SearchWidget;
 vSW.queryParam(xParam);
 } else {
 var bWidget2:IBaseWidget;
 bWidget2 = SiteContainer.getInstance().widgetManager.getWidget(id) as IBaseWidget;
 var vSW2:SearchWidget = bWidget2 as SearchWidget;
 vSW2.queryParam(xParam);
 }

Is there something here that has changed in 2.2?

Molly,

In my enhanced Search Widget there is a PDF called Enhanced Search Widget URL Search Configuration.pdf that has all the code changes that are updated for Flex Viewer 2.x try looking there.

question:
can the ?EXT take just a single set of coords? i am interested in having it zoom to a pt instead of a poly.

Jon,

Sure here is the code to change in the MapManager.mxml

            //map load complete
            private function mapLoadComplete(event:MapEvent):void
            {
//My Add
    map.zoomSliderVisible = false;
    map.logoVisible = false;
    
    try
    {
     if (ExternalInterface.available)
     {
      var timer:Timer;
      var result:URLVariables = new URLVariables();
      var urlSubstring:String = ExternalInterface.call("window.location.search.substring", 1);    
      if (urlSubstring && urlSubstring.length > 0 && urlSubstring != "debug=true")
      {
       result.decode(urlSubstring);
       // Parse URL
       var xExt:String;
       var xUrlParam:String;
       if (result["EXT"])
        xExt = result.EXT;
       
       if (!xExt == ""){
        var extArray:Array = xExt.split(",");
        var extent:Extent = new Extent(Number(extArray[0]), Number(extArray[1]), Number(extArray[2]), Number(extArray[3]),map.spatialReference);
        map.extent = extent;
       }
      }
     }
    }
    catch (error:Error){}
//End My Add
            }

to use it just append something like: ?EXT=644988.5757,1173575.0875,645690.0041,1173863.1558 to the url.

Glenn,

Nope... You would have to modify it to use a MapPoint instead of an extent.

The way that I dealt with this was to use field calculator to generate an extent based on a point location. Basically you just pick the scale you want, figure out how many meters that corresponds to, and then add or subtract half of that value from the point location to the 4 extents.

Steve,

I've successfully modified the code to pass a parcel ID in the URL. The map opens and zooms to the parcel which has been overlaid by a graphic. I'm attaching a text file with explanations and code.

Marc

Marc,
are there any changes to this code for it to be 2.3.x compatible?

glennhazelton

mark, i dont see the attached txt file.
love to have give it a try.

Glen,

I made this ability pretty easy (well documented), and very configurable in the eSearch widget. Have you looked at it?

Marc,

I have not moved to 2.3.x, but I just took a look at it and found that the function where the code gets inserted no longer exists. That may be the end of it. You might try Robert's eSearch widget solution.

Marc

Glenn,

The txt file is in message #9 of this thread. I just checked it and it opened fine. But if you are using Flex Viewer version 2.3.x, then it won't work anyway and you'll be better off trying Robert's eSearch widget solution.

Marc

Robert,

I just took a look at your latest eSearch 2.3.2 documentation, specifically the PDF about configuring the URL Search, and found that you also used the mapLoadComplete function in MapManager.mxml. But that function no longer exists in Flex Viewer 2.3.1. That's the same function I replaced for the solution I used. What are your thoughts on this? [edit -- never mind -- I see that your URL Search function is only for Flex Viewer 2.2. So, what next?]

Thanks,
Marc

Marc,

Actually it works fine in Flex Viewer 2.3.1 also. Even though esri removed the mapLoadComplete function I have you add it back and use it for my purposes instead.

Robert,

Thanks. So, if you put the function back in, where do you call it from? Do you restore the map.AddEventListener line in the protected override function partAdded where it was before? If it's this simple, then maybe the solution I was using will still work as well.

Marc

Marc,

It will work just fine. So you can go back to your function.

Marc, I just tested it and it works.




protected override function partAdded(partName:String, instance:Object):void



{
   map.logoVisible = 
false; 
   super.partAdded(partName, instance);
   if (instance == map)
   {
       var cssStyleDeclaration:CSSStyleDeclaration = styleManager.getStyleDeclaration  ("com.esri.ags.components.supportClasses.InfoWindow")
       cssStyleDeclaration.setStyle("backgroundColor", getStyle('contentBackgroundColor'));
       styleManager.setStyleDeclaration("com.esri.ags.components.supportClasses.InfoWindow", cssStyleDeclaration, true);
       map.addEventListener(MapEvent.LOAD, mapLoadComplete);
       changeESRILogo(map);
   }


}

And then your mapLoadComplete function, I just placed inbetween these two functions:
override protected function getCurrentSkinState():String
and the
private function changeNavigationbyWidget(event:AppEvent):void
