Button stays active and no action taken ?

[StrongBeaver]

When clicking on the 'Group Invert' button; the button remains active and nothing happens when the follow script is applied to a group.

 var ui = new Window ("dialog");
 var uiConvert = ui.add("button",undefined,"Group Invert");
 var uiFind = ui.add("button",undefined,"Group Finder");
  ui.orientation = "row";
 ui.show();
 uiConvert.onClick = function() {
 var mDoc = app.documents[0];
  var nGroup = mDoc.groupItems[0].selected;
 if (nGroup >= 0) {
 app.executeMenuCommand("ungroup"); 
 }
};

ui.show() must be placed after uiConvert.onClick event handler:

var ui         = new Window("dialog");
var uiConvert  = ui.add("button", undefined, "Group Invert");
var uiFind     = ui.add("button", undefined, "Group Finder");
ui.orientation = "row";
uiConvert.onClick = function() {
  var mDoc   = app.documents[0];
  var nGroup = mDoc.groupItems[0].selected;
  if (nGroup >= 0) {
    app.executeMenuCommand("ungroup");
  }
}
ui.show();

everything else is good

The UI has to encapsulate everything

Although why does the button after triggered stay enabled or "blue" ?

I think it's a good questions to Adobe developers

Oh, maybe they can answer ?

I think that behaviour of event handlers and function Window.show() - it's a norm for Illustrator ExtendScript.

The blue color of the last pushed button does not a bug - it's a feature of the Illustrator cc2017 !
