Delete Graphic in Edit Mode Retains Vertices on Map - Possible Bug

Kathleen_Crombez — Mon, 07 Dec 2015 23:22:32 GMT

Using the JavaScript API (currently using version 3.15).

I draw a graphic on the screen. Then I call the editor tool to edit the graphic.

If I delete the graphic while the editor tool is enabled, the graphic disappears, but the edit tool vertices remain on the map.

Not sure if this is by design, or just something the developers overlooked.

The only way to terminate the edit mode and remove the vertices from the map is to select a different graphic for editing.

It seems to me that if the graphic is deleted, the edit mode should be terminated on that graphic naturally.

Kathleen,

I can not duplicate what you are seeing in either of these samples that use 3.15

Robert Scheitlin, GISP,

Not sure how those samples were set up, but I found this issue to occur when deleting graphics using the clear function.

I have a graphics layer called drawingGraphicsLayer in which I set up an onClick event to activate the editor tool bar.

drawingGraphicsLayer.on("click", function (evt) {

dojo.stopEvent(evt);

editToolbar.activate(Edit.MOVE | Edit.SCALE | Edit.ROTATE | Edit.EDIT_VERTICES, evt.graphic);

});

Here you can see I have drawn an arrow on the map and and activated the editor tool by clicking on the graphic.

I have a button to delete all graphics which invokes drawingGraphicsLayer.clear();

If that command is called while the editor tool is activated on the graphic the vertices remain on the screen.

I have found that adding the following onClick event on the map will remove the vertices by clicking elsewhere on the map.

map.on("click", function (evt) {

editToolbar.deactivate();

});

However, it seems like the editor tool should naturally be deactivated on all graphics if they are deleted using the clear function.

Kathleen,

I tend to disagree. It should be your responsibility as the developer to deactivate the edit tool before you use the GraphicLayers clear method since you are not using the edit tool to delete the feature.

How am I to use the edit tool to delete the graphic when there is no delete option on the edit tool?

According to the documentation, the edit tool only allows the following constants...

MOVE, SCALE, ROTATE, EDIT_VERTICES, and EDIT_TEXT

Kathleen,

If you look at the one sample this is how they are handling it:

layer.on("click", function(evt) {
  event.stop(evt);
  if (evt.ctrlKey === true || evt.metaKey === true) { //delete feature if ctrl key is depressed
  layer.applyEdits(null,null,[evt.graphic]);
  currentLayer = this;
  editToolbar.deactivate();
  editingEnabled=false;
  }
  });

But you could very simply just call editToolbar.deactivate() before you call GL.clear();

Kathleen,

So I created an app to show you specifically what I was telling you to do and I found that I could not reproduce what you are finding.
