The problem I experience with shortcut keys that stop working is
unique to Rev. At first I thought maybe it was related to Edit menu
getting out of synch with the current state (e.g. whether or not
there was a selectedField). But recently I've come across something
that makes me think otherwise.
In two different apps I'm working on I experienced loss of
functionality in my shortcut keys. It turns out that rawKeyDown just
stopped being sent to my stack. The only way to get rawKeyDown
messages back was to click on a object that could become the
focusedObject. Once I did that, rawKeyDown was received again and
shortcut keys worked.
Both of my apps share something in common - when the user double-
clicks on a field with locked text in a scrolling group I create a an
editable field in the group that allows text entry. I then insert a
frontscript which will save the contents and delete the editable
field. As soon as this editable field was deleted the rawKeyDown
messages stopped being sent. By focusing on an object in the handler
that deleted the editable field I was able to fix the problem.
I'm still investigating what is going on and trying to reproduce this
in a simple example stack but haven't been able to yet. What I've
found out so far is that right after I delete the editable field,
focusedObject returns the card id. Using a monitoring handler, I
noticed that focusedObject starts returning empty shortly
thereafter. This is when rawKeyDown stops working. The docs say
focusedObject should return the current card if no object is selected.
So perhaps this odd behavior is related to the one that is causing
problems for the Rev IDE. If so, it would explain why they are
having such a hard time reproducing as it could be related to what
stacks people are working on. I don't know. Hopefully this will
help shed some light on the subject though.
