suspendHistory breaks activeHistoryState

Question

Hi,I've found that when you try to get the activeHistoryState after a suspendHistory call, you get the wrong one, namely the previous - e.g.
var doc = app.activeDocument;
$.writeln(doc.activeHistoryState); // [HistoryState DemoFile.jpg]
doc.suspendHistory ("TEST", "doc.activeLayer.name = 'Something'; doc.activeLayer.name = 'SomethingElse';");
$.writeln(doc.activeHistoryState); // [HistoryState DemoFile.jpg]
// shouldn't be [HistoryState TEST] ?
Why is it this way? Any workaround?I've also tried using doc.historyStates.getByName('TEST'); but fires an error - it seems like the state hasn't been created.Any help is really appreciated, thank you!Davide Barranca---www.davidebarranca.comwww.cs-extensions.com

FYI,Michel Mariani suggested this workaround:var doc = app.activeDocument; $.writeln(doc.activeHistoryState); // [HistoryState DemoFile.jpg] doc.suspendHistory ("TEST", "doc.activeLayer.name = 'Something'; doc.activeLayer.name = 'SomethingElse';"); app.refresh();$.writeln(doc.activeHistoryState); // [HistoryState TEST] It adds the usual, unwanted delay app.refresh adds, but at least the history state is the right one.

Photoshop scripting also runs into this problems and revert document to state previous to the execution of the script when a script move/resize tramsform a layer when there is an active selection. I reported that bug years ago Adobe acknowledge the bug but does not care to fix it. I saw at least one scripting thread where a user was backed up three states they were bitten three times.

Still seems to be in all release of Photoshop.

I believe Photoshop scripting expected that something it did regarding the active selection would create a history state it need to remove but the history state was not created because the script had suspended history state.

Adobe even assign a programmer to fix a bug I reported about Bad option added to CS4 when Adobe added the Adjustment panel. The Programmed never removed the bad options, They are still in the Adjustment Panel fly-out menu.

It would be better if Adobe fixed acknowledged bugs not just log them..
