Map.SetSpatialReference() deactivates tool in Pro 3.0 - possible bug

KarenMeinstein

I have a MapTool where when the tool is activated, and also during mouse down events with the tool, the active map spatial reference is changed using MapView.Active.Map.SetSpatialReference(mySpatialReference);

In Pro 2.9 and earlier this worked fine, but now in Pro 3.0 the SetSpatialReference line of code deactivates my tool and the map Explore tool (i.e., the pointing hand cursor) is activated.   Note that the spatial reference DOES change correctly. The problem is the tool being deactivated.  This seems like a bug in Pro 3.0.  Has anyone else encountered this or know if a work around?

Hi Karen, 

 

If you have access to the tool code, can you see whether the following works for you as a possible workaround to the tool deactivating?  

 

  
  private bool ignoreToolDeactivation = false;
  protected override async Task OnToolActivateAsync(bool active)
  {
    var map = MapView.Active.Map;
    var wkid = map.SpatialReference.Wkid;

    // wkid 102038 = world from space
    if (wkid != 102038)
    {
      await QueuedTask.Run(() =>
      {
        ignoreToolDeactivation = true;
        var sr = SpatialReferenceBuilder.CreateSpatialReference(102038);
        map.SetSpatialReference(sr);
      });
    }
    else
      ignoreToolDeactivation = false;
    await base.OnToolActivateAsync(active);
  }

  protected override Task OnToolDeactivateAsync(bool hasMapViewChanged)
  {
    if (ignoreToolDeactivation)
    {
      // dont let the tool deactivate
      FrameworkApplication.SetCurrentToolAsync(this.ID);
    }
    return Task.CompletedTask;
  }

 

 

Thanks
