Popup with error
I hope this isn't another embarrassing error on my part
I have a script that opens a popup window. But in Firefox, for some reason on the first load I get this error:Code:
this.fireVisibilityChanged.createDelegate is not a function

It means you have an invalid element object. Generally this is caused when the id passed to getEl() is invalid (like if there is more than 1 element with that id) or the element passed has no id and you didn't tell getEl to generate one (second param true). In my latest dev copy I have turned on generateId by default so the second param is no longer required.
In the latest beta (downloadable on the latest blog post) it returns null now instead of a busted Element object. That should help debugging for sure.
