Redo Undo

[Shavit Roee]

Hello
I have a major problem with the Undo Redo mechanism.
I am adding a LineConnector to the diagram executing an undo command Redo command and then another undo results as the following bug ,
Doing the same thing with a Rect Works just fine.
See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

Hi Shavit,

Thank you for your interest in Syncfusion Products.

I am afraid that I was not able to reproduce this issue. I have tested this issue by adding LineConnector to the diagram with our latest version Essential Studio 2008 Volume 1. Please refer the below video clip:

Please have a look at the above video clip and let me know if I am missing something.

Thanks,
Melba

Hello Melba,
I have found the bug regarding the Undo/Redo, it took me a lot of time to figure it out, the problem has to do with a Node property "EnableCentralPort = false" which causes the exception. I think I also found a bug regarding the "HistoryManager.GetRedoDescriptions()" function that sometimes throws an exception.
Please run the example I am sending you to verify that I am correct
1. Add a line press undo, redo, undo it will cause a crash.
2. Unmark the remark on
string[] str = HistoryManagerRedoTransactionsNumber();
Add a line change its position 2-3 times and press undo then redo until the application crashes ;

Thanks,
Roee Shavit
