Hi Willr
I have discovered that the userforms module doesnt work with the post 2.4 SS branch. This line in FieldEditor.ss
<% require javascript(sapphire/thirdparty/jquery-ui/jquery-ui-1.8rc3.custom.js) %>
needs to be replaced with
<% require javascript(sapphire/thirdparty/jquery-ui/jquery-ui.custom.js) %>
Thanks
Guy
