🚀 go-pugleaf

i have experienced a similar problem a couple of times probably because of
bad coding practice! - when dynamically creating components on the fly and
then adding event listeners to these i found that sometimes when i
re-instantiate and add the component to the screen in a single run that
there is still an event listener registered with this component. i reckoned
this was because i have not removed the event listener when removing the
component, so that when the component appears again within the app, i re-add
my event listener to that component and there are now two, or three etc
event listeners listening, which will cause the associated event to fire
multiple times etc. the simple solution is of course to instantiate the
event listener that you are going to add with a name and then add/remove it
by name when you add/remove the component from the gui - this fixed it for
me. hope this was of help but i've not answered one of these before so i
guess i might be talking twiddle!
