Bug 359931

Description Jeremy Flicker 2011-10-04 18:43:05 EDT

Build Identifier: Version: 3.6.1 Build id: M20100909-0800

In the method ProjectionViewer.handleVerifyEvent(VerifyEvent)

It is possible for the super.handleVerifyEvent to be invoked twice.
This can result in two customizeDocumentCommand sessions, which in turn can result in double insertions into a projection viewer when there are AutoEditStrategies that act on the forwarded DocumentCommand.

In my editor, i have an AutoEditStrategy that customizes the DocumentCommand in order to customize the text that is inserted into the editor when the user types.  This behavior is causing duplicating effects in the editor when in Block Selection Mode, for example, the user presses the letter 'd' and two 'dd' is inserted into the editor. 

Reproducible: Always

Steps to Reproduce:
1. Create an editor with an AutoEditStrategy
2. Have that strategy invoke the addCommand() method on the document command to add an additional text insert/deletion
3. Set the doit flag to the original DocumentCommand to false
4. You will then see duplicate insertions when the user types a key in the editor when they are in block selection mode
