Layer is not shown in the TOC after load shapefile

LeonardoAraújo — Thu, 13 Dec 2012 17:44:40 GMT

Hi all,

I'm trying to use the Load Shapefile widget (http://www.arcgis.com/home/item.html?id=bc6a88cf51364d9ea767347954363d7d) and am having a problem after loading a file. The features are loaded successfully but the TOC does not display the new layer. Could anyone help me on this?

Leonardo,

That is because the ShapeFile widget adds the shapefiles to a graphics layer and not a normal type that would show in the TOC.

Dear Robert,

I've tried changing the GraphicsLayer to FeatureLayer according to the code below but had no success. The layer is displayed in the table but the features were not shown on the map. Am I doing something wrong?

while (shpReader.hasMore()) {
array.push(new Graphic(...
}

var features:Array = [];
for each (var geometry:Geometry in GraphicUtil.getGeometries(array))
{
features.push({ geometry:geometry });
}

featureSet.spatialReference = map.spatialReference;
featureSet.features = features;
featureLayer.featureCollection = new FeatureCollection(featureSet);
featureLayer.id = layerName;
featureLayer.name = layerName;
map.addLayer(featureLayer, 1000);

Leonardo,

The featureCollection needs a LayerDetails

var layerDetails:LayerDetails = new LayerDetails(); featureLayer.featureCollection = new FeatureCollection(featureSet, layerDetails);

I will be coming out with an enhanced Shapefile widget very soon that handles re-projecting the shapefile and adding each shapefile and labels as different layers in the TOC, as well as other features.

Thank you very much Robert! It worked perfectly. I'll be waiting for your new widget and certainly will use it in my application.

Thank you Robert, I am trying to use your new widget but there must be some problem with my geoprocessing service. The reprojection task never ends and a empty alert window is shown. You could tell what can be?

Leonardo,

Did you read the readme.txt where it said you need to use an ArcGIS Server 10 Geometry Service.

Yes, I am using ArcGIS Server 10 SP4 geoprocessing service.

Leonardo,

You are meaning to say Geometry Service right?... And you have you Flex Viewers main config.xml point to your Geometry Service?

Right, I meant Geometry Service. I'm pointing to my own service in the config.xml file.

Can you try and use my live preview site to test your shapefile zip?

Can you try pointing your main config.xml to this instead of your?

<geometryservice url="http://tasks.arcgisonline.com/ArcGIS/rest/services/Geometry/GeometryServer" />

I did a deploy the application to my web server and there everything was fine. For some reason I am not able to run the application from my IDE.

Leonardo,

Strange I run from my Flash Builder IDE all the time. Do you have your Flex Build Path in your project pointing to an"Output folder URL"?

Hi,

I'm also having problems showing layer in the TOC. I use ArcGIS Viewer for Flex 3.0 and Adobe Flex SDK 4.6. I use uncompiled versions of widgets. When I upload a .zip file it reproject and shows on the map correctly, but it does not show up in TOC. I get �??Generating TOC Legend�?� message which never ends. It does not stop showing this message even after I remove shape file. Otherwise TOC widget works perfectly. I tried using layer list and my shapefile does show up there. Any idea how to fix this?

Thank you,
Petra
