SyntaxEditor for WPF Web Languages Add-on Crash on code typing

Hi Karlen,

Sorry I'm trying but I'm not getting any crashes.  Can you explain how to make it happen in a bit more detail and provide all the exception info (message, stack trace, etc.)?

Here is my XAML for window:

<Window
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:syntaxeditor="http://schemas.actiprosoftware.com/winfx/xaml/syntaxeditor" x:Class="WpfApplication1.MainWindow"
        Title="MainWindow" Height="350" Width="525">
    <Grid>

        <syntaxeditor:SyntaxEditor HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
            <syntaxeditor:EditorDocument>
                <syntaxeditor:EditorDocument.Language>
                    <syntaxeditor:JavaScriptSyntaxLanguage/>
                </syntaxeditor:EditorDocument.Language>
            </syntaxeditor:EditorDocument>
        </syntaxeditor:SyntaxEditor>

    </Grid>
</Window>

 Code-behind file:

namespace WpfApplication1
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }
    }
}

Exception type: ArgumentOutOfRangeException

Thanks but we need more detail on the steps to make it happen.  For instance, what are the exact contents of the editor before step 3?  And please explain more about what you mean at step 3 since I'm not clear on what is written there.

The content of editor is blank document.

So I start typing just example js code:

function func()

 Pressing "whitespace" key, then pressing 'Enter' key with curly bracket '{' application just crashes.

the final code without crash should be:

function func()
{

}

Hi Karlen,

Sorry but I'm still not able to get any problems to show up.  It's the "then pressing 'Enter' key with curly bracket '{'" part that I am not understanding.  Do you mean you are somehow pressing them at the same time or just pressing Enter and then afterwards, '{'?  Please explain that in more detail, thanks!

Also are you sure you're on the latest version?  Which exact build are you on?

Hi Actipro Team!

Yes, I'am pressing at the same time Enter key with {

I've started evaluating build 0591.

Regards,

Karlen

Hi Karlen,

I've been trying to repro this but still cannot.  I've tried for quite a while now and it works properly no matter how much I type the Enter and { around the same time.  I really need to be able to reproduce this reliably to be able to work on any sort of code change for it.

I see. So at least I may provide just my machines configurations if it could help:

Windows 7 x64 SP1 Russian Language Pack; .NET Framework 4.5; VS 2012 Update 4

Windows Server 2012 x64; .NET Framework 4.5; VS 2012 Update 3

At this time I'am evaluating SyntaxEditor and would like to use/ship with my product. But this strange bug is confusing.

Hi Karlen,

There must be some step that I am doing differently from what you are doing to make this happen since it shouldn't matter what Windows version you are on (unless you are using some form of IME input).  Are you using IME input?  I'm trying to follow your instructions exactly but it's never crashed for me.

Could you possibly try to make a new simple sample project and automate it?  For instance, add a SyntaxEditor to a window and do this code in response to a button:

editor.Document.SetText("function func() ");
editor.Caret.Offset = editor.ActiveView.CurrentSnapshot.Length;
editor.ActiveView.ExecuteEditAction(new ActiproSoftware.Windows.Controls.SyntaxEditor.EditActions.TypingAction("{", false));
editor.ActiveView.TextChangeActions.InsertLineBreak();

When I do that, it's working fine.  I even tried switching the last two lines to see if it would happen but it didn't.

Hi, Actipro Team!

I'am not using any kind of IME input.

I've tried with your sample code provided, but there is no crash behavior.

So I've recorded a video how to reproduce this behavior - link at SkyDrive.

Hi Karlen,

We still have been unable to reproduce it, even doing the same as what you do in the video.  Can you write us at our support address and reference this post?  We'd like to send you a link to a preview build of the next maintenance release to try, so you can see if you can make it happen there as well.

Hi, Actipro Team!

I'll write to your support address, but would like to know the way you are assuming, i.e.

1) By using https://support.actiprosoftware.com/Main/frmTickets.aspx

2) Or by support@...

Karlen

Hi Karlen,

Yes, either of those go to the same private ticket system.

Hi Karlen,

Thanks again for the sample.  We were able to debug it with that.  This problem is now fixed for the upcoming maintenance release.
