InvalidOperationException when collecting feature

NilsRydh

I have created a task for the ArcGIS Mobile application. I try to select FeatureType programatically and then use SketchCollectionMethod for collecting data of that feature type.

Everything seems to work fine until I save the data, then I get an exception. This is what I do:
1. Register CollectionStarting and CollectionCompleted events
2. Find the feature type among the Mobile project data
3. Initilize a feature of that type and start the SketchCollectionMethod.
4. When the GeometryCollectionCompleted event is fired, I show an EditAttributesDialog
5. Try to save using feature.SaveEdits();
6. InvalidOperationException is thrown and the Mobile Cache is corrupted and won't open the next time i start the application. I have attached the stack trace, but it isn't very helpful.

Do I have to show the FeatureTypePage for this to work, or am I missing something?

When I have problem with things I generally put a try and catch around it, for example:
Try
{
SOMETHING (in this case _featureDRAWN.SaveEdits();
}
Catch (Exception ex)
{
System.Windows.Messagebox.Show(ex.toString());
}


I personally can't see anything wrong with the code it make sense to me, all I can suggest is the tools I used to make it work.

C:\Program Files (x86)\ArcGIS\Mobile10.0\DeveloperKit\Samples\ApplicationFramework\Windows\SimpleDataCollectionExtension

That's the sample I used. In this case you don't need to show the FeatureTypePage, hence in my Mobile application I am trying to avoid that page. Instead I have a button on the form for each feature we would collect.

If the use click on the first button, it passes the name of the featurelayer, in which I can determine the featuretype and then create a new feature using the featuretype.

I do suggest making proper EditAttributePage event handlers for OK and Cancel like in the sample provided above. I doubt this will make a difference but its worth a shot.

I have attached my code, which is a modified version of the SimpleDataCollection extension.
