mxUndoManager undo() does not work after applying layot (for exampel mxCircleLayout). What can be the problem? PS: I'm using 0 size for unlimited history.

mxUndoManager undoManager = new mxUndoManager(0);

var listener = function(sender, evt) {



graph.getModel().addListener(mxEvent.UNDO, listener);

graph.getView().addListener(mxEvent.UNDO, listener);



try {


var layout = new mxCircleLayout(graph);


} catch (e) {

throw e;


finally {

var morph = new mxMorphing(graph);

morph.addListener(mxEvent.DONE, function() {

Remove the graph.getModel().beginUpdate() inside the try block.

It does not help, I accidentally added it when preparing an example.

And it looks like that undo() starts to work after some minutes (or mb dozens minutes) after layout was applied.

Looks like there is some background process starts on layout applying and undo starts to work after this process ends his work.

Can't reproduce, works for me. I've emailed an example.

Thank you for your active support. Your example works correctly, but it seems that something else has an impact, but I can not understand what is it. It seems that time after which undo manager starts to work dependends on the number of items in graph and the type of layout.

Tried to call undo() via setTimeout after layout applying and it works fine, so the real problem was that key press event is not fired after layout applying. I'm using mxKeyHandler: keyHandler.bindKey(keyCode, function(evt) { ... }

Tomorrow, I'll try to understand why this is so.

Hey, can you please email me Gaudenz's example? Thanks a lot.
