Browser rezise breaks Event/Command mapping in a Module
Hey guys,
Thank you for reading this. We are using Robotlegs 1.1 with Joel Hooks modular utility to build an application and have spotted a bug.
When browser is resized manually, this seems to completely break the mapping of Commands to Events inside a loded module Context. Modules load into a TabNavigator, so re-loading the broken module re-maps everything when Context.startup() is run again. However re-sizing browser again inevitably leads to the same failure.
Has anybody come across this strange behaviour?
Many thanks.
Igor

Hi Igor - could you post the code that is breaking (ie your context mapping) - obviously with any sensitive stuff stripped out.
Even better - if you can create a minimal version that demonstrates the breakage, we can take a closer look.
The absolute best - if you can do it - would be a test added to the test suite that currently fails and should pass once the bug is fixed.
Thanks,
Stray

Hey Stray,
I have just found the reason for this fault. It is nothing to do with RL. Inside each module I had a cleanup() method ModuleMediator unmapping all events, commands, singletons etc when the module is removed. It was previously added to
viewComponent.addEventListener(Event.REMOVED_FROM_STAGE, cleanup);
weirdly this was firing when the application was being resized as part of the browser window. It didn't even occur to me to check for it first.
Now I have changed the above line to:
viewComponent.parent.addEventListener("unload", cleanup, false, 0, true);
parent in this case is ModuleLoader and it all works fine.
Thank you so much for looking into it.
Igor

Great - glad you found it, and good to have it in the knowledge base for people who have this problem in future.
Thanks,
Stray
