syntaxEditor crashed when Document.Text is set

SyntaxEditor for Windows Forms Forum

I looked thru the forums and didn't see the bug I am experiencing reported.

I have the syntax editor placed on a tab.

The following line work successfully when the tab that has the syntax editor has focus:

syntaxEditor.Document.Text = script;

When a different tab has focus and that line is called I get the following stack trace:

System.IndexOutOfRangeException: Index was outside the bounds of the array.

Even if I catch the exception, the syntax editor become corrupt, switching the tab with the syntax editor on it, generates endless exceptions that basically kills the app and the syntax editor has a red X thru it with no text displayed.

If the text I am setting it larger than the existing, no crash occurs. If the text I am setting is less (a java script function was removed) the crash occurs. However, the crash only occurs if the script editor is not visible. If the editor is visible and has focus, setting a smaller text works fine.

Our usage if that we use a drop down to switch between several java sript files for the user to edit, i.e. client side and server side java script.

Hi Charles,

First please try the latest maintenance release to see if it happens there. If it still does then please email us a simple sample project that shows it happening so that we can debug it.

I think this bug was fixed a few maintenance releases ago.
