Multiple selection does not respect grid anchors

Hi. I have been trying the diagrams for quite a bit now and the product works well for all of my needs.

Anyway, I have a problem that I can't fix. When I select a single item and drag it, the item moves inside the grid (I have set setShowGrid to true) correctly, following the anchors, but when I select multiple items (nodes and links), these are moving freely inside the diagram without following the anchors.

Could you suggest a solution to this problem? thank you.

Hi,

I wasn't able to reproduce at first, and found AllowMultipleResize being enabled in my test project leads to aligning correctly, so try this as a solution if you don't mind the resizing -

diagram.setAllowMultipleResize(true);

With it disabled, it seems there's some error accumulating and showing after you move same selection a few times? Our developer will check that.

Regards,

Great! With this property it works! I resized and moved a lot of elements multiple times and everything works fine, thank you (maybe i suggest you to add this method in the documentation if there isn't, i couldn't find it).

I have one last thing to settle: If i move an element to the bottom edges of the canvas to resize it, when I reload the diagram everything is fine. By the way, if I do the same thing to the top edges, when I reload the diagram it looks like the diagram moves everything to the top corner and some nodes superimpose others. I will attach two screenshots.

What do you mean by reloading the diagram? Loading from a file, or regenerating it from data and running some layout code?

If applying layout code, please post it.
