Runtime problem in migrating FB4 project to FB4.5

[bobba1]

Hello,

I am having issues with a project originally authored in FB4, and migrated into the new FB4.5.1 framework. I migrated it according to the protocols, but still get an error. While running the project, there is a point when a user clicks on an image and then a handler should take them to a new view. Now, when they click, the following runtime error message appears -

TypeError: Error #1009: Cannot access a property or method of a null object reference. at spark.components::Scroller/focusInHandler() at flash.display::Stage/set focus() at mx.core::UIComponent/setFocus() at mx.managers::FocusManager/setFocus() at mx.managers::FocusManager/mouseDownHandler() at flash.events::EventDispatcher/dispatchEventFunction() at flash.events::EventDispatcher/dispatchEvent() at mx.managers::SystemManager/mouseEventHandler()

If I click on "continue" (I am running Flash player debug), the application appears to work properly. Any idea what this error message might be, and how I  might fix some of the code to address it? Thank you.

Hi!

I found a solution for my case, hope it fits you.

I'm using a TextArea in a host component that is being used as a PopUp. Changing this host component to a BorderContainer solved the problem.

Hope it helps.

Best regards,

Jorge

Thank you for the reply, Jorge.

I'm not using any pop-ups, but o will double check host components. Thanks for the thought.

Best
