I am getting a weird error when trying to call addPopup() to add a custom popup. It's been working the whole time until I made some minor changes today that broke it, and now I can't seem to get it back in working order.
My code (fired on button click to open popup):
And in ViewEditDeletePopup.mxml I just have a Panel, which contains an HBox, which in turn contains 3 buttons.
When addPopUp is called, I get the following error: (apart from the error, the popup opens correctly and is completely functional. It's just the error that pops up every time.) My popup mxml does implement IFlexDisplayObject. It's funny because I have another popup elsewhere in the app that I create in the exact same way, but it does not produce the error. However, replacing the ViewEditDeletePopup.mxml with the other popup also doesn't work. I think the problem lies within PopUpManager itself.
