Error while drawing features

#1

Hi,

We’re using TG Web Edition 9.0.0.0 with Oracle layers overlays. Tile image requests are generating errors drawing features with the following message:

Object reference not set to an instance of an object.
at xRM=.SUE=.TUE=(Byte[] wkb)
at ThinkGeo.MapSuite.Core.Feature.GetBoundingBoxCore()
at ThinkGeo.MapSuite.Core.LineStyle.uxs=(RectangleShape currentExtent, IEnumerable1 featureList) at ThinkGeo.MapSuite.Core.LineStyle.DrawCore(IEnumerable1 features, GeoCanvas canvas, Collection1 labelsInThisLayer, Collection1 labelsInAllLayers)

at ThinkGeo.MapSuite.WebEdition.LayerOverlay.DrawCore(GeoCanvas canvas, Object nativeImage, RectangleShape canvasExtent, GeographyUnit mapUnit)

Can you help us on this regard? It seems like there is no BBOX for features!

We will wait your feedback.

Hi Bruno,

We are unable to recreate this issue by our testing data. But I guess this issue may be caused by the Invalid features. Please try the following steps to get the invalid features and modify them manually.

  1. Get all of the features by calling the oralceFeatureSource.GetAllFetures().
  2. Call the feature.IsValid() method for every feature in the features get in #1.
  3. Filter the invalid features and modify them manually.

If it’s not the cause of the issue. Could you please share some data for us and provide us a sample?

Thanks,
Peter

Hi Peter,

We’ve added a link to WeTransfer with a Visual Studio project where you can replicate the error.
