Harbs, After debugging I see something like this:
http://images.devs-on.net/Image/jg5EXavR0Yo3N065-Obszar.png We are doing undo on _memento, but it doesn't have our deleted text in the MementoList, because our text is inside delSelOp.undo(). Doing _memento.undo() we are getting these error, but probably if we do undo on delSelOp we will have correct data. Just my findings after long debugging :) Piotr ----- Apache Flex PMC piotrzarzyck...@gmail.com -- View this message in context: http://apache-flex-development.2333347.n4.nabble.com/DISCUSS-Release-Apache-Flex-4-14-0-tp43390p43757.html Sent from the Apache Flex Development mailing list archive at Nabble.com.
