Subwindows throw JS errors


I’ve been trying to add a modal window to my application, while it does add the window I get these errors when the subwindow is displayed and when I try to resize it:

I’ve searched everywhere but haven’t found an answer anywhere.

I’m running Vaadin 7 Beta 11, Grails 2.2.0, Vaadin 7 Plugin 1.7.0 beta 11 for Grails on Linux Mint 14

I hope you guys can help me out.

There was recently a client-side error if a sub-window or Panel has no content set, so it might be that.

It was exactly that, thanks.

I feel kinda silly for not even trying that.
