Feature edition errors

ab1 — Fri, 28 Dec 2012 09:10:05 GMT

Hello,
I've created a feature editor, of a puntual feature layer, in a flex 3.1 client. The feature layer is served by a feature service in ArcGIS Server 10.0.
When I try to update or delete features (I didn't try creation), I get errors eventhough the changes are made in the database.
The errors are like these :

TypeError: Error #1009: Il est impossible d'accéder à la propriété ou à la méthode d'une référence d'objet nul.  at com.esri.ags.components::Editor/saveUnsavedAttributes()  at com.esri.ags.components::Editor/attributeInspector_saveFeatureHandler()  at flash.events::EventDispatcher/dispatchEventFunction()  at flash.events::EventDispatcher/dispatchEvent()  at mx.core::UIComponent/dispatchEvent()  at com.esri.ags.components::AttributeInspector/dispatchSaveFeatureEvent()  at Function/http://adobe.com/AS3/2006/builtin::apply()  at mx.core::UIComponent/callLaterDispatcher2()  at mx.core::UIComponent/callLaterDispatcher()   TypeError: Error #1009: Il est impossible d'accéder à la propriété ou à la méthode d'une référence d'objet nul.  at com.esri.ags.components::Editor/featureLayer_editsCompleteHandler()  at flash.events::EventDispatcher/dispatchEventFunction()  at flash.events::EventDispatcher/dispatchEvent()  at mx.core::UIComponent/dispatchEvent()  at com.esri.ags.layers::FeatureLayer/http://www.esri.com/2008/ags/internal::editHandler()  at mx.rpc::AsyncResponder/result()  at com.esri.ags.tasks::FeatureLayerTask/handleApplyEdits()  at Function/http://adobe.com/AS3/2006/builtin::call()  at com.esri.ags.tasks::BaseTask/handleResultEvent()  at mx.rpc::AsyncResponder/result()  at mx.rpc::AsyncToken/http://www.adobe.com/2006/flex/mx/internal::applyResult()  at mx.rpc.events::ResultEvent/http://www.adobe.com/2006/flex/mx/internal::callTokenResponders()  at HTTPOperation/http://www.adobe.com/2006/flex/mx/internal::dispatchRpcEvent()  at mx.rpc::AbstractInvoker/http://www.adobe.com/2006/flex/mx/internal::resultHandler()  at mx.rpc::Responder/result()  at mx.rpc::AsyncRequest/acknowledge()  at DirectHTTPMessageResponder/completeHandler()  at flash.events::EventDispatcher/dispatchEventFunction()  at flash.events::EventDispatcher/dispatchEvent()  at flash.net::URLLoader/onComplete()

In the code I have declared the editor inside the <fx:Declarations> along with a geometry service:

<esri:Editor id="mainEditor" map="{mainMap}" geometryService="{geometryService}" />

And I assigned the following method to 'initialize' attribute of the application:

protected function application_initializeHandler(event:FlexEvent):void    {     mainEditor.featureLayers = [arrets];         }

where "arrets" is the name of the feature layer I want to edit.

Do you have any idea of why the errors appear?

Regards.

Layachi,

Can you show how your are adding your layer in your code? Does your FeatureLayers url end with FeatureServer/# ? Is the layer you are attempting to edit coming for an SDE enterprise geodatabase?

<esri:FeatureLayer id="arrets" url="http://serverIP:8399/arcgis/rest/services/myService/FeatureServer/0" />

Yes, it's coming from a SDE geodatabase.

Layachi,

If your editor is NOT suppose to be in your declarations section as it is a visual component.

Thank you Robert for your answers.

I don't want any visual editor. Because of that I put it in the declaration section.

Layachi,

Then you need to look at the Edit without editor sample.

Or Just set the editors visibility to false.

I put the editor inside a window and put visible="false".
=> I get no errors.

Thanks Robert 🙂
