[4.2.0 beta 2] It would be great to have a tree's beforecheckchange event
Hello ExtJS team,
Many events have its "before" counterparts and it is cool.
It would be great to have a "beforecheckchange" event for a tree as well. For example, to prevent check/uncheck by returning false.
Also a property for a node like "checkReadOnly" would be also excellent.
Thank you for your attention.
P.S. I noticed "Thank you for reporting this bug." after starting the thread. I thought this forum is for any topic related to beta. But seems not. So, it was a wrong place for a feature request, apologize.
Thanks for the report! I have opened a request in our bug tracker.
