Hello all,

I want to change text in a editor after a user typed something in. For this purpose I added a ITextListener to my TextEditor.

When calling the replace method of from the ITextListener's textChanged method I get the exception attached below. Is a there a workaround existing so that I can change the text in an editor based on what a user is typing without using the replace method of the IDocument interface?

Best Regards,

Ralph

You can't change the contents of a document while it's in the middle of firing a change notification. This sounds like the job of an org.eclipse.jface.text.IAutoEditStrategy .

Hi,

this looks exactly like what I want. For everyone interested, I found this tutorial http://ydtech.blogspot.de/2011/09/eclipse-pde-everything-about-editor_10.html

Thank you!
