onDrawStart and onDrawEnd not working for RModify interaction

[stefgootzen]

The following event handlers do not execute when changing the feature geometry. I'm on RLayers currently on 2.2.0.

 <RInteraction.RModify
    onDrawStart={() => {
      console.log("start");
    }}
    onDrawEnd={() => {
      console.log("end");
    }}
  />

It works for me, there must be some other conditions. Do this in the Draw.tsx example:

<RInteraction.RDraw
    type={'Circle'}
    onDrawStart={() => {
        console.log('start');
    }}
    condition={altKeyOnly}
    freehandCondition={never}
/>

You will see the message when you draw a circle.

There you put the onDrawStart on the Circle, however, the RModify interaction also have those event handlers, those don't seem to work.

I noticed that in the Openlayers Spec they use:

modifyend (ModifyEvent) - Triggered upon feature modification end
modifystart (ModifyEvent) - Triggered upon feature modification start

Ah yes, indeed. You can simply pass onModifyStart instead of onDrawStart and it will work - it is only the TypeScript type that is wrong.

Ah yes, that's it. Thanks for the quick replies!
