Hello,
Maybe the Cocoon Code c(sh)ould be changed to make this possible?
Imho it would be very "natural" to allow the javascript to cancel the
action.
And it shouldn't be too difficult to implement this.
I thought about it as well, but it's not as easy as it seems though. The
moment where the event listeners are called depends on the action type
[...]
So allowing event listeners to cancel the action would require to change
this behaviour, which was designed to allow listeners to take
complementary actions to the main one.
In the end, my opinion is that if conditional action is needed, then
it's better to write the few corresponding lines in a regular fd:action
that has no built-in behaviour like row-actions and repeater-actions do.
Yes your right, but thing is that the action does not trigger the
validation process. I tried form.validate() and
form.endProcessing(true); and didn't success, and i don't have the time
atm to investigate this any further. What i'd like to do is to trigger a
validationError if the wrong row shall be deleted.
Then you can simply call someWidget.setValidationError(...) from within
your event listener.
