kineticjs drag & drop - no release inconsistency

问题

First of all drag and drop works correctly in my stages in version 4.3.0, so I just want to understand why I get the following problem with 4.3.3.

I have three stages. One sits in a container in a document in an iframe. The others sit in containers in the iframe's parent document, one displaying a complex layout of shapes and the other a single simple shape for testing. The document in the iframe which controls all the action has a viewfinder overlay that drags and drops correctly. However the shapes in the layout and test stages do not release on mouseup.

Any idea about what's going on would be appreciated ... I like to try and keep up to date.

Well, since I can't see any of your code I can only help so much, try doing the following.

For each shape that you have, add this attribute:

  dragOnTop: false

example:

  Kinetic.Rect({
      fill: 'blue',
      dragOnTop: false
  });

Let me explain how I found an answer by first amending the structure. There is a holding file which contains shared files and two iframes - one for a machine-like index and one for a display each with its own scripts. The main shared file is nameset.json which lists all the objects and their key/value couplets. These are sent to 'fill out' the machine and display frameworks. I thought I could do the same with the Kinetic Global object, referring to the Global.stages array. It seems obvious now that each of the iframes needs its own Kinetic link (rather than pointer) and these need to be used to marry machine/display interactions like the map shown here. Anyway all the dragging and dropping works smoothly as promoted. Thanks for that!

Will mark as answered but if anyone has any comments would be pleased to read them.
